Margaret D. Foster, seen in her lab. The original caption by the National Photo Company is "Miss Margaret D. Foster, Uncle Sam's only woman chemist, Oct. 4/19" - that's possibly a bit misleading, though she definitely was the first female chemist in the United States Geological Survey team. Foster died on this day in 1970 at the age of 75.
