Sad to hear of Jane Goodall’s passing at 91. Was extremely lucky to spend a couple hours with her at @STLScienceCtr in 2022.

We remember and honor the remarkable life of Dr. Jane Goodall. Her visit to the Saint Louis Science Center during Becoming Jane was a moment we’ll never forget. Her legacy of compassion, curiosity, and conservation will continue to inspire generations. Thank you, Dr. Goodall.

Starting today, you may notice some exterior cleaning around the Science Center! Over the next 2 months, our building & pedestrian bridge will be getting a fresh wash. During this time, certain areas may be rerouted for your safety. Thank you for your patience!

Underrated truth: The voices in your head aren't yours. They're recordings. Your parents. Your teachers. Your bullies. Your exes. You've been replaying other people's opinions so long you think they're your thoughts. They're not. Turn off the tape. Find your actual voice.
