Ever heard of the Dobsonian telescope? Or of the San Francisco Sidewalk Astronomers? The amateur astronomer John Dobson who founded the Sidewalk Astronomers and did so much more besides died on January 15, 2014, leaving a legacy thats sure to endure.

John Dobson is a hero to all who love astronomy, telescopes, and astronomy for the public. Hes been called the Pied Piper of Astronomy, and the Star Monk. As described in his bio on the website of the San Francisco Sidewalk Astronomers, he is:

arguably one the most influential personalities in amateur astronomy in the last 50 years. He has almost single-handedly revolutionized backyard astronomy by bringing it out to the street, making it accessible for anyone who has ever looked up in wonder, and asked Why?

Born in Peking (Beijing), China in 1915 to a family of musicians and intellectuals, Dobson joined the Vedanta Monastery in San Francisco in 1944, becoming a monk of the Ramakrishna Order. He built his first telescope in 1956 and was said to be so fascinated with what he saw that he said to himself:

Everybodys got to see this.

Telescopes at the time were complicated and expensive pieces of equipment, and Dobson was a monk, with no money. He ultimately developed what has come to be known as the Dobsonian telescope with an inexpensive mounting thats unique is its simplicity, moving up and down, left and right. The design for these telescope mounting has been duplicated by countless amateur astronomers who wanted to find an inexpensive way to build what they needed to peer up at the night sky.

But Dobson didnt stop there. In 1968, he founded the San Francisco Sidewalk Astronomers, who began bringing astronomy to the streets and to parks. His efforts inspired amateur astronomers around the world to share their equipment and their knowledge with the public at regular star parties. If youve ever attended a star party, its perhaps thanks to John Dobsons early efforts.

A note at John Dobsons Facebook page yesterday said:

It is with great sadness and heavy hearts that we have to report the passing of Mr John L. Dobson. He died peacefully this morning, January 15th, 2014, in Burbank, California. He was 98. John leaves behind a son, many close friends, and legions of friends, fans, and admirers around the globe.

ISAN 7 (International Sidewalk Astronomy Night) will be held in honor of John on March 8th. Amateur astronomers worldwide can join in and celebrate his life by carrying the torch that John lit back in 1968 when he co-founded the San Francisco Sidewalk Astronomers.
