Jarvis was the eldest son of Joseph Charles Jarvis, of Harpenden. In 1901 he married Bessie Woodfield, the third daughter of Edwin Woodfield from Enfield. They had two sons and two daughters. John Jarvis received his secondary education at The Grocers' Company's School in Hackney.
Residence
From 1921 until his death, Jarvis lived at Hascombe Court in Surrey, 500m west of the village of Hascombe, 5 km south of Godalming. The garden was designed under Jarvis's ownership by Gertrude Jekyll in 1922, and extended by Percy Cane in 1928.
In early 1934 he was elected as High Sheriff of Surrey, and shortly afterwards visited Jarrow, a shipbuilding town on Tyneside which had been particularly badly hit by the Great Depression. The Depression caused a collapse in demand for ships, and the closure of Palmers shipyard in Jarrow, leading to 80% unemployment in the town. Jarvis launched an appeal named the "Surrey Fund" which eventually raised £40,000; the funds were used to buy materials to enable men in Jarrow to continue working, on tasks such as the constructing playgrounds and sports facilities and the redecoration of houses. Using his own wealth, Jarvis also bought the decommissioned liner RMS Olympic for a reported £100,000 and had the ship brought to Tyneside to be broken up, followed in 1938 by the liner Berengaria. The breaking of Berengaria was promised to directly employ 200 men in skilled and semi-skilled tasks in the new Jarrow Shipbreaking Company, while the metal was to be used in Jarvis's new metal industries in the area, which employed several hundred people. Through Jarvis's efforts, several other new businesses were established in the Jarrow area. Jarvis also bought unemployed miners from Jarrow to Hascombe Court, his country estate in Surrey, where they built a Japanese style water and rock garden. Set against the scale of the economic problems in Jarrow, the impact of Jarvis's efforts is contested. In a letter published in The Times on 2 October 1936, Jarvis listed some of the achievements of the fund as a "step in the right direction". However, on the following day Jarrow MP Ellen Wilkinson praised Jarvis's support for the town but criticised "his over-sanguine optimism", noting that the employment generated had been small-scale and temporary. Wilkinson complained that charitable works were inadequate, and that a solution to the problem required addressing the underlying cause, which was the forced closure of the shipyard. For his efforts, Jarvis was made a freeman of Jarrow in 1935, but the ceremony on 4 June was boycotted by Labour Party councillors because Jarvis had been selected as a Conservative candidate for the coming general election.
Parliament
Guildford's Conservative MP Charles Rhys announced in January 1934 that he would not contest the next election. At a meeting of the Central Council of the Guildford Division Conservative and Unionist Association on 25 February, Jarvis was invited to be the National Conservative candidate at the next election, and it was reported on 9 March that he had accepted. However, the parties in the National Government had agreed not to oppose each other at elections, so a question arose as to whether the National Government-supporting candidate for the forthcoming vacancy in Guildford should be a Conservative or a Liberal. S. Stopford Brooke, who had contested Guildford for the Liberal Party at the 1929 general election, had stood aside in favour of the Conservatives at the by-election in August 1931 and at the general election later that year. Brooke announced in February that he had resigned from the Liberal Party, and intended this time to stand as National candidate "without prefix or suffix". He was supported by local representatives the Liberal, Conservative and National Labour parties. However, in August 1935, Brooke's candidacy was halted by the local National association, which announced that since the collaboration of parties in the constituencies had not developed across the country at large, "no useful purpose would be served by running a purely National candidate in this division in support of this principle". At the general election in November 1935, Brooke signed Jarvis's nomination papers. The only other candidate was Andrew Campbell of the Labour Party, who was a stranger to the constituency and had a weak local organisation. Jarvis was elected with nearly 75% of the votes, and was made a Deputy Lieutenant of Surrey in 1936. He was re-elected in 1945, and held the seat until he stood down from the House of Commons at the 1950 general election. In November 1943 he wrote to The Times newspaper to summarise his experiences in Jarrow, asserting that it was better to bring work to people in depressed areas than to encourage them to move in search of work. Jarvis died on 2 October 1950, aged 74.
