John L. Dobson 1915-2014
John Dobson, the self-taught stargazer who designed the powerful, inexpensive Dobsonian telescope, died January 15, 2014 at a hospital in Burbank, California. He was 98. His death was confirmed by the Burbank chapter of Sidewalk Astronomers, an international organization that John Dobson helped found in 1968. John Dobson was arguably the most influential person in amateur astronomy in the last 30 years. He almost single-handedly revolutionized amateur astronomy by making deep space accessible to millions. Through his free star parties and slide shows, he encouraged both young and old to think about the Universe and observe its beauty with their own eyes.

John Dobson was a former monk and self-taught stargazer who developed a powerful, inexpensive telescope that almost anyone could build and showed thousands how to do it during five decades as one of public astronomy's most influential evangelists.

Called the "Johnny Appleseed of amateur astronomy", the lanky, pony tailed Dobson started building telescopes in the 1950s when he was a monk at the Vedanta Monastery in San Francisco. His passion for the hobby led to his expulsion, freeing him to become a roving ambassador for the simple joys of studying the nighttime sky.

"He really wanted to just share viewing the sky with people," said Anthony Cook, astronomical observer at Griffith Observatory. "He created a hobby and a type of telescope that ensured that people could build their own and look farther across the universe than was possible for most people before his time."

Dobson used cheap or salvaged materials such as ship portholes and cardboard tubing to make his telescopes, the most radical feature of which is a simple, sturdy and highly effective wooden mount that allows users to easily point the scope at any spot in the sky.

His design was eventually embraced by commercial manufacturers, who advertised the telescopes as "Dobsonians." They remain one of the most popular telescopes on the market.

Dobsonian telescopes have made important contributions to astronomy, including the discovery in 1995 of Comet Hale-Bopp, the farthest comet ever discovered by amateurs. One of its namesakes, Tom Bopp, was using a Dobsonian.

Bob Alborzian, coordinator of the Burbank Chapter of Sidewalk Astronomers, who had known Dobson since 1968, said he once urged Dobson to patent his design. Dobson refused. "He said these are gifts to humanity," Alborzian recalled. "His goal was to open astronomy to the common man."

Dobson was born September 14, 1915, in Beijing. His mother was a musician and his father taught zoology at Peking University. Nervous about political unrest in China, his family relocated to San Francisco in 1927. He earned a degree in chemistry from UC Berkeley in 1943 and went to work in the defense field.

An atheist since high school, he began to study Eastern religions after attending a lecture by Swami Ashokananda of the Vedanta Society. In 1944 he joined the Vedanta Monastery in San Francisco, where he was asked to reconcile the order's teachings with science.

That assignment led him to build his first telescope in 1956. He scavenged for materials, including a 12-inch porthole glass from a marine salvage yard that he sanded into a telescope mirror.

When he was done, he peered at the moon and was profoundly moved. "Everybody's got to see this," he said.

Transferred in 1958 to the order's Sacramento monastery, he began building telescopes in earnest. Soon he took to stealth, smuggling parts into the monastery in fertilizer boxes after his superiors told him his activities were inappropriate for a monk.

He was often away from the monastery to help neighbors in the community construct their own scopes. That is what the other monks thought he was doing when they decided to expel him in 1967.

According to his biography on the Sidewalk Astronomers website, he wasn't neglecting his monastic duties that time but was weeding the lawn behind a monastery wall. Nevertheless, he was thrown out.

He hitchhiked to San Francisco, where he began teaching and setting up his telescopes on street corners. With the air of a carnival barker, he enticed passersby to look deeply into the heavens. "Come see the Sun!" he shouted, sometimes while twirling a lariat.

Brusque and witty, he explained the cosmos in easily understood terms. "If the Sun were the size of a basketball," he often said, "Jupiter would be the size of a grape, and the Earth would be the size of a very small grape seed."

In 1968, he formed the San Francisco Sidewalk Astronomers with Bruce Sams and Jeffrey Roloff, who had built telescopes under his tutelage. Soon, he was barnstorming the country, setting up his scopes in shopping center parking lots and national parks - anyplace, he said, "where dark skies and the public collide."

With chapters across the country and abroad, Sidewalk Astronomers now has upward of 10,000 members, said Director Donna Smith.

In 1978 Dobson was invited to give a series of lectures at the Vedanta Society of Southern California and began to spend part of each year in Los Angeles. He lived at the Vedanta center in the Hollywood Hills, often hiking to Griffith Observatory, where he led public events such as a 12-hour telescope-building marathon in the mid-1980s.

His life was chronicled in films, including the 2005 documentary "A Sidewalk Astronomer," directed by Jeffrey Fox Jacobs. Also in 2005, he lectured in Australia.

In his 90s, Dobson was still a gypsy proselytizer for astronomy, lecturing and giving workshops as far away as Russia and China.

Used to the most Spartan accommodations, he was known to sleep inside the scope's cylindrical tubes when he was on the road.

"There's one thing nice about sleeping in a telescope," he said in 2007. "You can't roll out of bed."
