California Academy of Sciences’ Steinhart Aquarium Celebrates 100 Years

Centennial celebrations include activations across the city, inside the museum, and more.

SAN FRANCISCO, CA (August 22, 2023)— The beloved Steinhart Aquarium at the California Academy of Sciences will mark a major milestone—its 100th anniversary—on Friday, September 29, with a wide variety of festive activities. Centennial celebrations will include a citywide scavenger hunt, a coastal cleanup community event in McLaren Park, pay-what-you-can museum admission on September 29, the publication of a new book, The Spectacular Steinhart Aquarium, iconic Steinhart animals projected on the Salesforce Tower, a 1920’s-themed NightLife, special exhibitions and programs, and more. For a complete list of activities see the Centennial Celebration Events section below.

“Steinhart Aquarium has been a cultural anchor for San Francisco since 1923. Grandparents who came to see the fishes when they were kids are now bringing their grandchildren to revel in the beauty and splendor of some of the most awe-inspiring aquarium displays anywhere on the planet,” says Academy Executive Director Scott Sampson. “And our impact extends beyond the museum walls: Whether it’s sending biologists to South Africa to help rescue and rehabilitate abandoned wild penguin chicks, advancing the science of coral reef regeneration, or engaging museumgoers and online audiences with high quality educational programming, Steinhart Aquarium’s impact can be felt worldwide.”

One of the most advanced and biologically diverse aquariums in the world, Steinhart Aquarium is home to nearly 60,000 inhabitants representing more than 1,000 species of live plants and animals. Its innovative exhibits include one of the world’s largest and deepest indoor living coral reefs and a four-story rainforest, and historically included architectural marvels such as the 60-foot diameter ring aquarium, the Fish Roundabout, and remarkable “firsts” such as the first great white shark displayed in an aquarium.

“For more than half my life I’ve been fortunate to be a part of this great institution, learning from passionate and talented colleagues and mentors, caring for beautiful and fascinating animals, and journeying to some of the most remote corners of the planet to study marine life,” says Senior Director of Steinhart Aquarium Bart Shepherd, who began working at the aquarium in 1996 and authored a new book titled The Spectacular Steinhart Aquarium. “I’m so proud of the impact that the Steinhart has had in our Bay Area community and beyond, and I am confident that the second century will be as remarkable as the first.”

Named for brothers who helped fund the aquarium, Ignatz and Sigmund Steinhart, Steinhart Aquarium first opened its doors on September 29, 1923, to an unprecedented crowd of 5,000. One hundred years later, Steinhart Aquarium has been a source of joy and wonder for nearly 150 million visitors, and remains dedicated to inspiring the public to explore, understand, and regenerate the natural world.

The oldest continually operating municipal aquarium in the United States, Steinhart Aquarium is a powerful leader in conservation and scientific research. As part of a major regeneration initiative called Hope for Reefs, Steinhart was the first U.S. aquarium to successfully spawn corals, making its researchers uniquely poised to inform restoration practices.

The Steinhart technical dive team regularly discovers new species from the deep coral reefs known as the “twilight zone,” as well as uncovers the human impacts these ecosystems face. The aquarium has also been a champion of endangered species through collaborative breeding programs, called Species Survival Plans, and continues to support wild populations like endangered African penguins inside the aquarium and in the wild.

Centennial Celebration Events The Academy will celebrate the Steinhart centennial throughout the month of September and anniversary year with a variety of events and activations:

Steinhart Aquarium Extraordinary “Firsts” and Other Accomplishments Steinhart biologists and scientists have propelled many scientific discoveries and advancements for nearly a century while educating millions of visitors:

The Many Homes of Steinhart Aquarium Steinhart Aquarium opened in September 1923 in a neoclassical building designed by architect Lewis P. Hobart, who played a significant role in rebuilding San Francisco after the 1906 earthquake and fires. This building remained relatively unchanged until a renovation and expansion from 1962 to 1963, followed by the fan-favorite Fish Roundabout in the 1970s.

Growing pains combined with the damage caused by the 1989 Loma Prieta earthquake helped nudge a move toward a new Steinhart Aquarium building and temporary relocation to Howard Street during construction of a new building in Golden Gate Park. When the arrestingly beautiful California Academy of Sciences opened in 2008 as the world’s greenest museum, it featured a serious upgrade to Steinhart Aquarium, including the 25-foot-deep Philippine Coral Reef as a stunning visual centerpiece.

Today eagle-eyed visitors can still spot some elements from the original aquarium in the new building, such as the iconic seahorse railing and historic Solon and Schemmel tiles that surround the Swamp habitat of modern-day mascot Claude the alligator with albinism.
