History of the Tacoma Astronomical Society

TAS was established in the late 1920s, and is the second oldest astronomical society in the country. In 1931, TAS was formally incorporated and officially known as 'The Tacoma Astronomical Telescope Makers'. This was during the Great Depression, and the group helped support each other in their enjoyment of astronomy and its costs.

Later, the Society changed its name to 'Tacoma Astronomer' and had many active members including Norm Pettinger who was the chief custodian of Tacoma Public Schools. Norm continued in the tradition of building telescopes as well as cameras, and he was one of the society's first astrophotographers.

The society changed its name once again during the 1970s and has since been known as the Tacoma Astronomical Society. During the late 1970s, Al George, a local businessman and avid amateur astronomer purchased an observatory and moved it to his home in Puyallup. It was named the Pettinger-Guiley Observatory (PGO) in recognition of the work and dedication of Norm Pettinger and Don Guiley.

The PGO remained an integral part of TAS until it closed in 2002, 25 years after it opened, when Al George retired. Through its many activities and events, TAS continues to be an integral part of providing resources to amateur astronomers and those interested in astronomy.
