Schweikher was a modernist who worked for, or with, the likes of David Adler, Fred Keck, and Philip Maher. He'd built the redwood and brick house, an early blend of Prairie School and International style, for himself in 1938, but was leaving to head up the architecture department at Yale. (He subsequently held the same job at what is now Carnegie Mellon.)
Alexander Langsdorf was an Argonne Lab scientist who'd done critical work on the Manhattan Project and petitioned the president not to drop the atomic bomb on cities. He was a founder of the Bulletin of the Atomic Scientists.
Martyl Langsdorf died last week at the age of 96. A widow for nearly 17 years, she'd continued living in the house under an agreement with the village. Here's the Reader story I wrote about it when she was still there to greet visitors.
The house is now managed by the Schweikher House Preservation Trust. Director Todd Wenger says its "fragile" condition prevents broad access, but they'll probably be opening it to the public more frequently. Check the Trust's website for possible future tours.
