John Deighton (November 1830 – May 23, 1875), generally known as "Gassy Jack", was a Canadian bar owner who was born in Hull, England. The Gastown neighbourhood of Vancouver, British Columbia is named after him.
Growing up in Hull, a major seaport, Deighton and his brothers Tom and Richard learned to sail. Tom and Richard apprenticed on British ships, but Jack did not receive that opportunity. However, this meant he could switch to sailing on U.S. ships. When the California Gold Rush hit, ships were in demand to transport cargo and people from New York to San Francisco. In 1850, this voyage around Cape Horn took 140–160 days. Deighton signed up to work a new clipper Invincible that could sail 400 miles a day and made the trip in only 115 days. The next journey was to Hong Kong. Deighton was 21 years old and Third Officer. Next, Deighton visited family at home in England and then returned to the U.S., never returning to England again.
Next, Deighton worked a gold claim in California, along with many others, until February 1858 when there was news of gold further north in a British territory known as New Caledonia. The Fraser Canyon Gold Rush had begun and Deighton sailed north along with thousands of others. The harsh winter took its toll on the prospectors but Deighton stayed for 5 years. He found no gold, though others did. New Caledonia was now the Colony of British Columbia. Traffic on the Fraser River was increasing as more miners arrived, but so far only American steamers were able to travel beyond Langley. Local boats were built to meet this need and Deighton piloted steamships and sternwheelers on the Fraser River for several years.
By 1864, Deighton was forced to pursue other lines of work as he developed health problems (swelling of the legs and feet).
Between 1862 and 1867, he ran a bar called the Globe Saloon in New Westminster, British Columbia. It was quite prosperous due to the Cariboo Gold Rush. But in 1867 when Deighton went out of town to visit the hot mineral springs near Harrison Lake, he entrusted the bar to an old shipmate, an American. On July 4 the celebrations got out of hand and Deighton returned to find his business ruined.
