Curator Q&A with Collin Vandewalle

It’s Been Wonderful Knowing You: Wildlife Conservation and Advocacy Through the Lens of Jay N. “Ding” Darling, the fall 2026 exhibition in the University of Iowa Main Library Gallery, features the work of a Pulitzer Prize-winning cartoonist from Iowa who was a major catalyst for the modern American conservation movement. From original cartoons and photographs to correspondence and natural history specimens, each item on display helps tell the story of Darling’s efforts to save America’s wildlife and natural resources.

Collin Vandewalle, Sackner Archive project archivist in Special Collections and Archives, co-curated the exhibition with Lindsay Moen, lead public services librarian in the same department. Through his research for the exhibit’s narrative and his time working closely with the Jay N. “Ding” Darling Papers, Vandewalle has gained significant expertise about Darling and his life’s work. 

Question: How did you become involved in the exhibition project, and what did you enjoy most about the process? 
Answer: I was a graduate student at the University of Iowa’s School of Library and Information Science and worked in Special Collections and Archives as a student lead. I worked specifically with the Darling Papers, so my then-supervisor—and now colleague—Lindsay Moen asked if I wanted to help her curate the Darling exhibit. I eagerly accepted so I could have a chance to apply all the knowledge I had gained about him. My favorite aspect of the process was the chance to tell a story about a side of Darling that not many people know about: his environmental conservation work.   

Q: What draws you most to the story of Ding Darling? 
A: I was drawn in most by his unwavering and unending zeal to help protect the natural resources of our country. Not many other people can claim they have worked so hard to save native migratory fowl, especially ducks, as Darling did, and I really admire that fervor.  

Q: As a curator, researcher, and Iowan, what does this exhibit mean to you personally? 
A:  I think it is important to tell the stories of prominent Iowans like Ding Darling and highlight the fantastic history this state has had when it comes to environmental conservation causes. It is so important to connect today’s Iowans to our scientific roots and reflect on how we can continue this kind of work in our state. I am proud that I can take all the research I have done and highlight this history through a curated exhibit. 

Q: When did you first hear about Ding Darling, and how have you worked with his materials over time?   
A: I had my first encounter with Ding Darling’s legacy when I was nine years old on a family trip to Florida. We went to the J.N. “Ding” Darling National Wildlife Refuge, and it was such a fantastic experience that I still remember it vividly 20 years later. I had my second encounter with Darling during my undergraduate experience at Drake University in Des Moines. I worked in the University Archives and Special Collections at the Cowles Library on campus and helped with another Darling exhibit that Drake hosted in 2017. I then worked with his papers for just over three years here at the University of Iowa. 

Q: Why is it important to have this exhibit in the Main Library Gallery?  
A: I think it is important that the campus community and the broader public gain a better understanding of just how robust the Darling collection is here at the University of Iowa Libraries. It is also amazing that we have the capability to showcase rare materials—like a presidential letter from Franklin Delano Roosevent to Darling, for example—in a safe and professional way through the Main Library Gallery.   

Q: What are some of the most surprising things you learned during your research? 
A: I was most surprised by just how interconnected Darling was with the politics and culture of his time. It seems like he knew every prominent figure from the turn of the 20th century. He met with Henry Ford, Theodore Roosevelt, Herbert Hoover, Walt Disney, Aldo Leopold, and many more celebrities.   

Q: What is your favorite object in the exhibit? 
A: My favorite object would be the letter from Franklin Delano Roosevelt (FDR) to Darling where he claimed that Darling had pulled the largest “heist” on the United States Treasury in American history. The letter is an amazing piece of history that highlights the tensions that FDR and Darling had for one another, particularly when it came to funding priorities. One will have to come to the exhibit to learn the context of this surreal letter.  

Letter transcript:

THE WHITE HOUSE
WASHINGTON

July 29, 1935.

Dear Jay:—

As I was saying to the Acting Director of the Budget the other day—”this fellow Darling is the only man in history who got an appropriation through Congress, past the Budget and signed by the President without anybody realizing that the Treasury had been raided.”

You hold an all-time record. In addition to the six million dollars ($6,000,000) you got, the Federal Courts say that the United States Government has a perfect constitutional right to condemn millions of acres for the welfare, health and happiness of ducks, geese, sandpipers, owls and wrens, but has no constitutional right to condemn a few old tenaments [sic] in the slums for the health and happiness of the little boys and girls who will be our citizens of the next generation!

Nevertheless, more power to your arm! Go ahead with the six million dollars ($6,000,000) and talk with me about a month hence in regard to additional lands, if I have any more money left.

As ever yours,
President Roosevelt

Honorable J.N. Darling,
Bureau of Biological Survey,
South Building,
Washington, D.C.
Letter from President Franklin Delano Roosevelt to Jay N. “Ding” Darling, July 29, 1935. Presidential Letters Collection, Special Collections and Archives, UI Libraries.

Q: What about Darling’s life and work do you hope visitors will take away from their time in the exhibit? 
A: I hope they leave the exhibit understanding that even just one person can spark change when it comes to environmental conservation. I hope they can see that Darling set a fantastic precedent on how we, too, can help protect the ducks and other wildlife of Iowa! 

Q: The Jay N. “Ding” Darling Papers in Special Collections have recently had some significant updates that make them even more accessible to researchers. What was your role in this project?  
A: My main role was making sure the Darling Papers were easier to use and more accessible to the public before the exhibit started. This meant that I rehoused a majority of the collection into newer archival grade boxes that will protect the material far longer into the future. I also spent a great deal of time intellectually reorganizing the finding aid so that researchers will have an easier time finding specific information from this extensive collection. 

Q: Is there anything else you would like to share? 
A: I want to thank everyone involved in making this exhibit come to life. It was a fantastic experience to co-curate this project at the start of my professional career.  

I hope everyone who comes to the exhibit leaves having learned at least one new thing about Darling or wildlife conservation. For those interested in a more in-depth look at Darling, I also worked with recent graduate student Hailee McCormick to create a 150-year timeline that spans Darling’s entire life and the institutions that make up his legacy up to 2026. That will be available online soon. 

It’s Been Wonderful Knowing You: Wildlife Conservation and Advocacy Through the Lens of Jay N. “Ding” Darling will be on display through Dec. 18, 2026. The Main Library Gallery is open daily. Learn more about open hours: lib.uiowa.edu/gallery. 

Mahler’s influence on James Dixon

The following was compiled by Cecil Campbell, exhibition and engagement student lead for the Main Library Gallery, and features select exhibition text by Sarah Suhadolnik and Katie Buehner.

During his considerable tenure as conductor of the Quad City Symphony Orchestra, James Dixon developed a reputation for programming modern compositions, which occasionally ruffled the feathers of his more traditional-minded audience members. Though he faced some objections, Dixon’s love for the music he conducted ultimately led to a wider appreciation in his audiences for newer or more avant-garde compositions. Amidst the repertory Dixon conducted, the works of Gustav Mahler (1860–1911) figure prominently.

Gustav Mahler was born in Bohemia but spent a great deal of his professional life as a composer and conductor in Vienna. His last few years were spent as the music director of the New York Philharmonic (1909–1911), the longest consistently operating orchestra in the United States. No composer of orchestral music exploited the orchestra’s grandness like Mahler. He composed sprawling symphonic works of such breadth that just one can fill an entire concert program. His nine mammoth symphonies require enormous performing forces (up to 500 musicians for the Eighth Symphony) and often stretch over an hour in length (up to 100 minutes for the Third Symphony), making attempts to keep the composer’s music in the public ear a major event. Fearing such a limited program would result in low ticket sales, the Tri-City (now Quad City) Symphony Orchestra avoided programming a Mahler symphony until 1979, when Dixon conducted Symphony No. 2, “Resurrection,” with Martha Sheil (soprano) and Anne Larson (mezzo-soprano) and choirs from Augustana College joining for the performance. The symphony—nearly an hour and a half long—elicited an awed and intense reaction from the crowd. 

In response to James Dixon’s conducting of Mahler’s second symphony, The Sunday Dispatch headline read, “Symphony concert of the decade,” with reviewer Bill McElwain in ecstasy over the “powerfully stunning performance of the Mahler Symphony no. 2.” 

Mahler once told another composer, “The symphony must be like the world, it must embrace everything.” His symphonic world included a wide array of musical styles and types, including sound effects evoking natural settings (e.g., birdsong, cowbells, bellowing horns), military marches, folk songs, chorales, funeral dirges, children’s music, and playful musical jokes. To conduct Mahler is to explore, with a complex and wide-ranging sound map, the many places in life where sound and music play a role. 

For his last performances with the Quad City Symphony Orchestra—April 9 and 10, 1994, at the Adler Theater in Davenport, Iowa, and Centennial Hall in Rock Island, Illinois—James Dixon selected Symphony No. 5 by Gustav Mahler. 

A composer with an incredible legacy and impact, the influence that Mahler had on Dixon comes as no surprise. The choice to perform one of Mahler’s symphonies for his last performance speaks to an open mind and considerable talent.

James Dixon’s lasting impact on the Quad City Symphony Orchestra 

The following was compiled by Cecil Campbell, exhibition and engagement student lead for the Main Library Gallery, and features select exhibition text by Sarah Suhadolnik and Katie Buehner.

In 1916, the Tri-Cities area—Rock Island, Illinois; Moline, Illinois; and Davenport, Iowa—was the smallest community in the country to support a full symphony orchestra. Now the Quad City Symphony Orchestra (QCSO), it is one of the oldest continuously operating orchestras in the United States.

In 1965, 37-year-old James Dixon was hired as the music director, appointing him steward of this legacy and the most recent director in a line of (at the time) seven before him. Although Dixon’s programming choices initially tested the tastes of audiences and administrators alike, he quickly garnered a reputation for steady leadership.

While learning to work with professional musicians, Dixon also grew into his role in the organization’s ongoing efforts to secure subscribers—members of the community who provide essential annual support. The care and discipline Dixon brought to his work transformed him into a local celebrity. While that may seem like high praise, Dixon’s celebrity status could be seen in more than just reputation. For example, at the time Dixon joined the QCSO as conductor, the organization had a modest budget. By the time he retired in 1994, budgets were significantly larger owing to his fundraising efforts. 

Dixon’s—and the QCSO’s—long-term investment in local community has paid large dividends. When one considers not only how important the orchestra is—and was—to its audiences, but to the musicians themselves, it makes his level of commitment stand out all the more. As one of the Quad Cities’ oldest community groups, it makes sense that the QCSO has played a significant role not just in the lives of area residents, but in many of its members’ lives as well.

In a now-archived blog post from the Davenport Public Library’s website, special collections librarian Sarah J. Wesson wrote, “The Symphony has remained a cohesive group, weathering storms and uncertainties together. Though none of the original [early] musicians remain, of course, many of the current members have been with the orchestra for a remarkable length of time.” 

After 29 years with the QCSO, James Dixon left an impression as significant as his orchestra. Former QCSO executive director Lance Willett said,  “I think it’s something that rarely, if ever, will be seen again in most communities. That kind of dedication and connection to a community…is the sort of relationship that exists very, very, rarely.”

Students investigate: eye-catching color in early children’s books

This series features the work and research of UI students. The following was written by Cecil Campbell, exhibition and engagement student lead for the Main Library Gallery. 

There are a number of hallmarks that we look for when identifying children’s media: big pictures, bold and eye-catching colors, large fonts. Children’s books especially are known for these traits, and have been since the 19th century, when they first became their own market and genre. Much like kid’s television shows today, stories often included a moral, or lesson, that extolled virtues like selflessness, patience, and kindness. 

Orbis Pictus by Johannes Amos Comenius was published in 1658. As one of the first instructional picture books for children, Comenius’s approach leaned heavily on visual learning and the use of instructional pictures and drawings. The goal was to teach learning comprehension through association: pairing words with images by placing them next to each other, until reading the given word independently recalled the corresponding image. Scholar Andrea Korda, in their journal article “Thinking with Pictures: Memory, Imagination, and Colour Illustration in Victorian Teaching and Learning,” writes that pictures were essential to Comenius’s methods not only because of their familiarity as iconic representations, but also because, according to Comenius, “children (even from their infancy almost) are delighted with pictures.” 

An important and equally iconic aspect of early children’s books was the chromolithograph. The process of the chromolithograph involved drawing a picture using an oil or grease-based ink and transferring that image to stone or metal plates and then printing over that image multiple times using differently colored versions of the same image. When put together fully, the colors of the different layers would produce a fully colored and detailed image that evoked the feeling of an oil painting, but at a fraction of the cost. Depending on how much detail a chromolithographer wanted in their picture, they might use anywhere from as little as eight plates to as many as forty to complete an image. Though used many times in children’s books, the chromolithograph was also used in collectible trading cards, Christmas cards, and calendars.   

Children’s books such as A Party of Six: A Movable Toybook by notable 19th-century author and bookmaker Lothar Meggendorfer also boasted interactive elements. These took the shape of flaps, pull tabs, and pop-up pictures that gave the book a feeling as though it were alive, as though it were a small puppet theatre instead of a book. These types of books enchanted children. Due to the significant amount of effort and detail they took to produce, these books typically were affordable only to richer and more affluent families.  

As both time and the children’s book industry progressed, chromolithography fell out of style, making way for modern machine color printing, which made color printing both cheaper and easier. Because of this, brightly colored children’s books, trading cards, calendars, and the like became much cheaper and accessible to people outside of the upper classes.  

A Party of Six is on display in the Main Library Gallery’s Paper Engineering in Art, Science, and Education exhibition, which showcases the fascinating world of paper technologies. Curated by Giselle Simón, Damien Ihrig, and Elizabeth Yale, this interactive exhibition invites visitors to explore paper dolls, flap books, pop-ups, tunnel books, volvelles, and books that use paper to make sounds while learning about their historical and contemporary significance. It is open to the public through Dec. 19, 2025.
