Quintin Hogg was a philanthropist and businessman. He was the fourteenth child and seventh son of Sir James Weir Hogg and Mary Claudine, the daughter of Samuel Swinton of the Indian civil service. He had four surviving older brothers, Sir James Macnaghten McGarel Hogg, first Baron Magheramorne (b. 1823), Stuart Saunders Hogg (b. 1833), Frederick Russell Hogg (b. 1836) and Stapleton Cotton Hogg (b. 1839), and four sisters, Isabella, Mary Rosina, Annie Claudina and Florence.
In 1871 Hogg married Alice Anna Graham, the daughter of the collector William Graham of Urrard, Perthshire. They had three sons, Douglas McGarel Hogg (b. 1872), Ian Graham Hogg (b. 1875) and Malcolm Nicholson Hogg (b. 1883), and two daughters, Elsie Florence and Ethel Mary. Their home address was 5 Cavendish Square.
Hogg attended Eton in 1858, leaving there in 1863 for the London office of the tea merchants Messrs. Thompson. In 1865 he entered the firm of sugar merchants Bosanquet, Curtis and Co. of 23 Rood Lane, E. C., where he advanced to a senior partner. The house was renamed Hogg, Curtis and Campbell. In the winter of 1864-65 he and Arthur Kinnaird started a Ragged School for boys and later a Youths' Christian Institute. From 1877 he was a director of North British Mercantile Insurance Co. In 1880 he became the founding editor of Home Tidings of the Young Men's Christian Institute.
Hogg used the income from his West Indian estates to take over the Regent Street Polytechnic in 1882 with the aim to educate young lower middle class men and women. New initiatives included a debating society, a savings bank, a Christian workers' union and a volunteer corps. He was behind the founding of the Polytechnic Movement in London. In January 1889 he was elected an Alderman of the first London County Council. He was also responsible for buying an athletic ground at Merton. In 1900 he published The Story of Peter, a series of religious addresses delivered at the Polytechnic from 1896 to 1897. He was a member of the Athenaeum Club and Wellington Club.
In 1877 James Chapman asked Hogg to give JW a letter of introduction to his brother James McGarel Hogg, who was Chairman of the Metropolitan Board of Works (#02158). JW wanted an interview with him concerning the external decoration of the White House, Tite Street, designed for the artist by E. W. Godwin. The Board withheld the lease until additional decorative details were added.
