Sir William James Lithgow, 2nd Baronet (10 May 1934 – 28 February 2022) was a Scottish industrialist and vice-chairman of Lithgow Group. In 1952 he inherited the Scottish shipbuilding company, Lithgows, which was established by his grandfather, William Lithgow. Economic and political changes, especially the nationalisation of British shipbuilding in the 1970s, prevented Sir William from simply continuing the family business, and he therefore led it in new directions, including engineering, salmon farming and other marine and agricultural matters. He described himself as an "industrialist and farmer".[1] Since 1999 his son James has been chairman of the Lithgow Group.
