James Whyte was the successor to David heron, the founder of the firm later to become James Whyte & Co, Glasgow. The company merged operations with a number of different entities, including Duncan McGregor & Co, where they sold sextants and opened branches in lucrative shipping areas. The whyte firm was associated with Lord Kelvin and later Bottomly & Baird establishing branches in London, Montreal, Newcastle Upon Tyne, Boston and New York.
