He was a Scottish-Canadian shipping magnate, financier, and capitalist. In 1819, his father Capt. Alexander Allan established the Allan Shipping Line, which became synonymous with transporting goods and passengers between Scotland and Montreal. Hugh received a parish education at Saltcoats before starting work in 1823 at the family's counting-house of Allan, Kerr & Co., of Greenock. In 1826, he moved to Montreal to work as a clerk for a grain merchant, William Kerr. By 1835, he was made a partner in the firm known as Millar, Edmonstone & Co. With his father's encouragement and capital, Hugh expanded the company's shipping operations, and J. & A. Allan (headed by his elder brother, James, in Glasgow) became closely involved with the building of the merchant fleet. By 1839 Hugh's younger brother, Andrew, had joined Edmonstone, Allan & Co. In 1851, Hugh was elected president of the Montreal Board of Trade. In 1854, he launched the Montreal Ocean Steamship Company as part of the Allan Line and took control of the Royal Mail contract between Britain and North America. By the 1880s, the Allan Line was the world's largest privately-owned shipping concern.

He also became a director of the Bank of Montreal, president of the Montreal Telegraph Company and he established coal mines in Nova Scotia and factories for textiles, shoes, paper, tobacco, and iron and steel in Central Canada.

Kathleen Allan, a native of St. John's, Newfoundland, Canada, is a conductor, composer and soprano, rapidly becoming internationally respected for compelling performances and engaging compositions. Her compositions range from intimate songs to larger works for choir and instrumental ensembles. She has a keen interest in contributing to the folk music tradition, both in her compositions and by reviving ancient songs in new arrangements. She has received two Newfoundland and Labrador Arts and Letters Awards (2007 and 2008), and in 2006, her composition for the saxophone quartet won the CBC's contest for young composers. Kathleen is also active as a choral and solo vocalist, having sung the lead role in the North American tour of Stephen Hatfield's chamber opera, Ann and Seamus, in 2007. She is currently studying composition with Stephen Chatman and voice with Bruce Pullan at the University of British Colombia in Vancouver, BC, Canada.
