Shedd Aquarium

The Shedd Aquarium is one of Chicago’s most significant scientific landmarks, located on the city’s Museum Campus along Lake Michigan. When it opened in 1930, it was the largest indoor aquarium in the world, a title it held for several decades. The institution was made possible through the philanthropy of John G. Shedd, a former president of Marshall Field & Company, envisioned an aquarium that would inspire the public by bringing the underwater world into an urban setting.

Planning for the aquarium began long before its opening. Shedd donated funds in 1924, but he passed away before the building was completed, leaving the project to be carried forward by the Chicago civic leaders. The aquarium was designed by architect Graham, Anderson, Probst & White, the same firm responsible for many of Chicago’s major buildings, including Union Station. Its Beaux-Arts and modernist design intentionally echoed the grandeur of classical architecture.

When it opened in 1930, the Shedd Aquarium represented a major technological and logistical achievement. At the time, maintaining diverse marine ecosystems indoors was extremely complex. Water filtration systems, temperature control, and transportation of live specimens all required innovative solutions. The original exhibits featured both freshwater and saltwater species, including fish from the Amazon, the Pacific Ocean, and the Caribbean. Many of these animals were transported long distances by rail and ship.

Throughout the mid-20th century, the Shedd Aquarium became a central part of Chicago’s Museum Campus alongside institutions such as the Field Museum and Adler Planetarium. It played an important educational role during a time when public science institutions were expanding across the United States. School groups, families, and tourists visited the aquarium not only for entertainment, but to learn about marine biology, ecosystems, and the diversity of aquatic life.

A major transformation came in 1991 with the opening of the Oceanarium, a large expansion that introduced marine mammals such as dolphins and beluga whales. Designed to simulate Pacific Northwest coastal environments, it marked a shift toward immersive, habitat-based exhibits. It also reflected broader debates within the museum and aquarium world about animal care, ethics, and the balance between education and conservation.

In the 21st century, the Shedd Aquarium has increasingly focused on conservation and environmental research. Its programs now extend beyond exhibit spaces into the Great Lakes region and global marine ecosystems. Efforts include habitat restoration, wildlife rehabilitation, and scientific research aimed at understanding the impacts of climate change and pollution on aquatic life.

Today, the Shedd Aquarium remains one of Chicago’s best institutions.Alongside its historical architecture and long-standing exhibits, it continues to evolve as a modern scientific institution committed to both learning and conservation.

Author Review:

Every time I visit the Shedd Aquarium, I am always impressed. I usually start in the Great Lakes exhibit, which is especially interesting because it highlights the fish and marine life native to Lake Michigan and the surrounding waters. It’s fascinating to move through the different habitats and see how the aquatic environments change from one region to another, showcasing species from all over the world. The aquarium also hosts live animal presentations, including beluga whale training, dolphin shows, and sea otter demonstrations, which are always a highlight of the visit. Each experience is very engaging, because the aquarium is so large, it’s a place you can return to many times without seeing everything at once. For students, there are discounted Chicago resident tickets, and occasionally free admission days for Illinois residents, so it’s worth keeping an eye out for those opportunities. From DePaul, it’s a 40 minute red line ride or a 20 minute car ride.
