William Blackwood (20 November 1776 – 16 September 1834) was a Scottish publisher who founded the firm of William Blackwood and Sons.
Blackwood was born of humble parents in Edinburgh. At the age of fourteen he was apprenticed to a firm of booksellers in Edinburgh, and he followed his calling also in Glasgow and London for several years. Returning to Edinburgh in 1804, he opened a shop in South Bridge Street for the sale of old, rare and curious books. He undertook the Scottish agency for John Murray and other London publishers, and gradually drifted into publishing on his own account, moving in 1816 to Princes Street. On 1 April 1817 the first number of the Edinburgh Monthly Magazine was published, which on its seventh number became Blackwood's Edinburgh Magazine. "Maga," as this magazine soon came to be called, was the organ of the Scottish Tory party, and round it gathered a host of able writers.
In 1829 he wrote to his son William in India telling him that he was moving from Princes Street to 45 George Street as George Street was "becoming more and more a place of business and the east end of Princes Street is now like Charring Cross, a mere place for coaches". His brother Thomas bought 43 and in 1830 Thomas Hamilton remodelled the entire frontage of the pair for the Blackwood Brothers. Thomas' shop operated as a silk merchant.
At the end of his life Blackwood was living at 3 Ainslie Place on Edinburgh's elegant Moray Estate in the West End. His bookshop was within easy walking distance, being located at 45 George Street.
William Blackwood died in 1834 and is buried in an ornate vault in the lower western section of Old Calton Cemetery.
William Blackwood married Janet Steuart (1780-1849) on 29 October 1805. They had a very large family. Most of his sons joined his publishing firm in some capacity. All are buried with him in Old Calton except where stated:
