The Dynasphere was a monowheel vehicle patented in 1930 by J. A. Purves, who called it “the high-speed vehicle of the future”; one source, however, reports that “while the [vehicle] could move along just fine, it was almost impossible to steer or brake.” You can watch a video here. (source)
This miniature reproduction of the West Parlor of George Washington’s Mount Vernon was crafted by Narcissa Niblack Thorne. The photo on the left shows the room being prepared for exhibition at the Baltimore Museum of Art in 1943.
Thorne’s detailed model rooms duplicate with historical accuracy the homes of the elite and wealthy from the late 13th to the early 20th century—and are on display at the Art Institute of Chicago, the Phoenix Art Museum, and the Knoxville Museum of Art. (Sources here and here)

Although he may not have paid £1,000 for a flea in 1914 (about $135,000 today), the banker Charles Rothschild was in fact a respected entomologist and an avid collector of fleas. He acquired some 260,000 specimens, including about 500 new species that he discovered, all of which are now part of the Siphonaptera collection in the British Natural History Museum. His daughter Miriam followed in his footsteps; her catalog of his collection (in collaboration with G. H. E. Hopkins) is considered a tour de force, and her book on parasites, Fleas, Flukes and Cuckoos, was a popular success. She was the first person to discern and describe the flea’s jumping mechanism.
