John Armstrong Garnett (24 June 1767 – 16 January 1831)[2] was the president of the Royal College of Surgeons in Ireland (RCSI) in 1810.
At this time he resided in Kildare-street, had a good surgical practice, and was an expert chemist, as I gather from the contents of his note-book of experiments.
He was, when the annual election of professors arrived, re-elected—not at his own request, but on that of C. H. Todd, who proposed to act as his locum tenens in the event of his illness continuing.
[2] In his History of the RCSI, Cameron gives a direct extract from Garnett's diary detailed his final days with Lord Edward Fitzgerald in Newgate Prison Dublin.
Fitzgerald, a leading Irish aristocrat, MP for County Kildare, was military director of the United Irishmen in the nationalist Rebellion of 1798.
