John Quiller Rowett

John Quiller Rowett (1876 – 1 October 1924) was a British businessman, philanthropist, and co-founder of the Rowett Research Institute.

Shackleton
A schoolfriend of Sir Ernest Shackleton at Dulwich College, Rowett was the sole financial backer for Shackleton's final Antarctic venture, the Shackleton–Rowett Expedition of 1921–1922, on the adapted sealer Quest. Rowett Island is named after him. In 1920, Rowett promised a cornerstone amount towards the new expedition. At this time, Shackleton gave Rowett the James Caird, in which Shackleton had made his famed 1916 open-boat voyage from Elephant Island to South Georgia. In late May 1921, after Shackleton had failed to raise the remaining funds elsewhere, Rowett agreed to finance the entire Shackleton-Rowett Expedition. After Shackleton's death, Rowett presented the James Caird to Dulwich College.

A mountain on Gough Island, a remote volcanic island of the Tristan da Cunha group in the South Atlantic, is named in his honour. After Shackleton's death in South Georgia, the expedition visited Gough Island in the tiny (125-ton) Quest, with parties going ashore from 28 May 1922 for a few days. When the expedition climbed and named Mount Rowett (made up of four peaks) it was thought to be the highest point on the island, at 836 m Thirty years later Edinburgh Peak, at 910 m, was found to be the highest point by the Gough Island Scientific Survey.

Death
On 1 October 1924, believing his business affairs to be on a downturn, Rowett killed himself aged 48. He died at 9 Hyde Park Terrace, London, leaving an estate valued for probate at £48,533.
