Adelheld "Heidi" Lange, St. Louis-born architect.

Adelheld (Heidi) Lange was born in 1878 at the stately house at Meramec and Iowa.

Lange wanted to become an architect but couldn’t attend school here because of the whole “being a woman” thing. She went to Switzerland to get her degree.

When she came back to St. Louis, she was hired by Theodore Link, the guy who designed Union Station. There are no buildings specifically credited to Lange, but shortly after she was hired, Link took a more modern approach to his buildings. The two were close, and it’s evident that Lange’s experiences in Europe played a huge influence on Link’s work.

A few years into her architecture career, she met and married Andre Roosevelt, the cousin of President Teddy Roosevelt. Andre Roosevelt was a filmmaker who enjoyed making exploitative films about Bali in an attempt to cultivate tourism. During this time, she got super into sculpting and took a break from architecture.

The couple ultimately separated, and Lange spent her later years living a quiet life in Connecticut.

Just figured it was worth noting that the first woman architect of St. Louis was born here.
