Henry Mackenzie FRSE (26 July 1745 – 14 January 1831) was a Scottish lawyer, novelist and writer. He was also known by the sobriquet "Addison of the North." While Mackenzie is now mostly remembered as an author, his principal income came from legal roles, ending in (1804–1831) his post as Comptroller of Taxes for Scotland, a well-paid post which allowed him to indulge his interest in writing.
Mackenzie was born at Liberton Wynd in Edinburgh on 26 July 1745. His father, Dr Joshua Mackenzie, was a distinguished Edinburgh physician and his mother, Margaret Rose, belonged to an old Nairnshire family.
Mackenzie was educated at the High School and then studied Law at University of Edinburgh. He was then articled to George Inglis of Redhall, who was attorney for the crown in the management of exchequer business. In 1765 he was sent to London to prosecute his legal studies, and on his return to Edinburgh became partner with Inglis, whom he afterwards succeeded as attorney for the crown.
Mackenzie had attempted to interest publishers in what would become his first and most famous work, The Man of Feeling, for several years, but they would not even accept it as a gift. Finally, Mackenzie published it anonymously in 1771, and it became instantly successful. The "Man of Feeling" is a weak creature, dominated by a futile benevolence, who goes up to London and falls into the hands of people who exploit his innocence. The sentimental key in which the book is written shows the author's acquaintance with Sterne and Richardson, but he had neither the humour of Sterne nor the subtle insight into character of Richardson.
A clergyman from Bath named Eccles claimed authorship of the book, bringing in support of his pretensions a manuscript full of changes and erasures. Mackenzie's name was then officially announced, but Eccles appears to have induced some people to believe in him. In 1773 Mackenzie published a second novel, The Man of the World, the hero of which was as consistently bad as the "Man of Feeling" had been "constantly obedient to every emotion of his moral sense," as Sir Walter Scott says.Julia de Roubigné (1777) is an epistolary novel.
