Sir James Key Caird, 1st Baronet (7 January 1837 – 9 March 1916) was a Scottish jute baron and mathematician. He was one of Dundee's most successful entrepreneurs, who used the latest technology in his Ashton and Craigie Mills. Caird was noted for his interest in providing financial aid for scientific research. He was one of the sponsors of Sir Ernest Shackleton's ill-fated Antarctic expedition of 1914 to 1916. The ship's boat, the James Caird, in which five of Shackleton's expedition made an epic voyage of 800 nautical miles (1,500 km) from Elephant Island to South Georgia, was named in appreciation of Caird's contribution. Biography James Caird was born in Dundee, and was the son of Edward Caird (1806–1889) who had founded the firm of Caird (Dundee) Ltd in 1832. The business was originally based in a 12 loom shed at Ashtown Works. The elder Caird was one of the first textile manufacturers to weave cloth composed of jute warp and weft. As the use of jute became increasingly popular, the Caird business expanded and thrived. Business career In 1870 James Caird succeeded his father as head of Caird (Dundee) Ltd. Under his leadership Ashton Works was re-built, expanded and equipped with the latest machinery. In 1905, the firm also took over Craigie Works, which had formerly supplied Caird with much of his yarn. Eventually the two works employed 2,000 hands. The Dundee Advertiser reported that Caird was a good employer who ran an efficient business which was also "a model of comfort for the workers". Family In 1873, Caird married Sophy Gray (1843–82), sister-in-law of the painter John Everett Millais. Her mental health was poor and Caird appears to have been rather neglectful towards her. They had one daughter, Beatrix Ada (1874–1888). His wife died at the age of 38 in 1882, possibly as a result of her longstanding battle with anorexia. The couple's daughter died in 1888 at the age of 14. After the death of his closest family, Caird increasingly devoted himself to philanthropic causes. Philanthropy and research funding James Caird made a substantial fortune from his business interests and reinvested much of it in his home city. He gave both the Caird Hall, which dominates City Square, and Caird Park in the north of city to the people of Dundee which also includes Mains Castle also known as Fintry Castle.
