Pittsburgh home, which included the world's first all-aluminum observatory dome!
In 1998, a Pennsylvania Historical and Museum Commission historical marker was

for many years.
Following a visit to America's first major planetarium,
Adler Planetarium in Chicago, Leo, and other AAAP members, lobbied foundations
and government officials to have a planetarium built in Pittsburgh. Their
efforts were successful with the opening of The Buhl Planetarium and Institute
of Popular Science on October 24, 1939. This was no small
feat, particularly in the middle of the Great Depression. Along with Allegheny
Observatory Director Nicholas E. Wagman, Leo was one of the first two
planetarium lecturers in the new facility.
Leo, at the urging of Harvard College Observatory Director
Harlow Shapley, worked hard to form the Astronomical League, which was
officially established in July of 1947, at a meeting at Fels Planetarium, Franklin
Institute in Philadelphia. One of the early organizational
meetings occurred in the Summer of 1940 at The Buhl Planetarium and Institute
of Popular Science in Pittsburgh;
however, World War II delayed the official establishment of the organization.
