Leo J. Scanlon

 The e-mail has just arrived. Tonight’s star party has been cancelled due to rain, clouds and muddy fields. I had an idea that this was going to happen. There is a good chance that tomorrow’s activities at the Wagman Observatory will be cancelled also. They tend to go hand in hand, plans for anything astronomical and bad weather.

    Even though it is doubtful, I am still keeping my fingers crossed for Saturday night. We can’t give up hoping!

    Along with Independent Bookstore Day, which won’t be hampered by rain, tomorrow is also Astronomy Day. This is a day when astronomers, both amateur and professional, share their knowledge, enthusiasm and love of the skies above us.

    This year’s Astronomy Day comes at a good time, it is the day before the birthday of a man who spent his life promoting astronomy. On April 30, 1903, Leo J. Scanlon joined the human race. 

    In his 20’s, he built his first telescope and not long after, he and Chester Roe formed the Amateur Astronomers Association of Pittsburgh. (AAAP) The club is still thriving. He was a plumber by trade but his real love was the stars above!

    Shortly afterward, he and friends, no doubt club members, designed and built the Valley View Observatory.

Almost ready for use

    Located in his backyard in the North Hills of Pittsburgh, it was the first observatory to have an aluminum domed roof on it. His design was copied by numerous professional observatories and gave us the image we picture when we think about observatories. It was dedicated in November of 1930 and stood there until 1997, 67 years later, when it was dismantled.

Leo and Albert Einstein

    In 1934, he sent a letter to Albert Einstein inviting him to visit the AAAP display at the convention of the American Association for the Advancement of Science which was being held in Pittsburgh. When Einstein arrived, he spent about 20 minutes at the display and later corresponded with Leo.

    During the same year, he was invited to watch the pouring of the glass which would form the 200” mirror for the Hale Telescope at the Corning Glass Works.

    Leo was influential in getting the city to build the Buhl Planetarium. After it was built, he and Nicholas Wagman, the director of the Allegheny Observatory were the first two speakers to give lectures at the facility.

    He also had a part in helping to create the Astronomical League in 1947.

    In 1998, a historical marker was placed on McKnight Road, not far from where his observatory sat. During the ceremony, he was told that an asteroid had been named after him!

    Leo passed away in 1999. He led quite an exciting astronomical life for a plumber. He is another person who set an example for us, of what a person can accomplish.

    While we watch the rain falling outside our windows, let's give a little thought to the people like Leo and think about how we can follow in their footsteps!

    Happy Birthday Leo, thanks for all you’ve done for us!
