ASTRONOMICAL CONTRIBUTION AND SIGNIFICANCE:

 

On June 9, 1929, he co-founded (with Chester B. Roe) the Amateur Astronomers' Association of Pittsburgh. With nearly 550 members, it is one of the largest such clubs in the nation.

 

On November 23, 1930, his private observatory was dedicated next to his North Side Pittsburgh home, which included the world's first all-aluminum observatory dome! In 1998, a Pennsylvania Historical and Museum Commission historical marker was dedicated near the site of the original Valley View Observatory, which was the unofficial observatory of the Amateur Astronomers' Association of Pittsburgh 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.
