The Thomas Planetarium was made possible through a generous contribution from Lowell and Tay Thomas.

Born in London in 1923, Lowell Thomas, Jr. was raised on a farm in New York. Like his world-famous father, he had a career as an author and film producer. An Air Force pilot during World War II, he graduated from Dartmouth College in 1948. He married Mary Taylor (Tay) Pryor, and they moved to Alaska in 1960 with their children, Anne and David.

Tay served two terms on the Anchorage School Board and was the author of An Angel on His Wing (1989), Only in Alaska (1969), and several other books. Lowell served eight years in the Alaska State Senate in the early 1970s, then as Lieutenant Governor from 1974 to 1978 with Governor Jay Hammond. He retired from a career as a mountain and glacier pilot and owner of Talkeetna Air Taxi in the mid-1990s, after flying mountain climbers and sightseers throughout the Alaska Range.

“Given recent space discoveries, it is now even more important for young people to have the chance to learn about astronomy and space.” Lowell Thomas, Jr.
