Brigadier-General Henry Beauchamp "Harry" Lassetter CB, CMG (19 March 1860 – 17 February 1926) was an Australian military officer.
Lassetter was born at Edgecliff and attended Cheltenham College, Eton and Sandhurst Military Academy; his father, Frederic Lassetter, was a prominent merchant. In 1880 he was a second lieutenant in the 38th Regiment, becoming lieutenant in the 80th Regiment in 1881. He was involved in an expedition to the Nile in 1884 and was promoted captain in 1887 and major in 1888, when he trained the Mounted Rifle Brigade. On 19 August 1891 he married Elizabeth Ann Antill at Picton. In 1895 he was promoted lieutenant-colonel and led the Australian detachment at Queen Victoria's Diamond Jubilee. He commanded the New South Wales Mounted Rifles in the Boer War (1901–02), during which time he was mentioned in despatches and created Companion of the Order of the Bath. In 1911 he became managing director of his father's firm, but he remained primarily involved in the military and took command of a territorial brigade in England in 1915, where he was promoted brigadier-general and created Companion of the Order of St Michael and St George (1917). In 1924 he returned to Sydney, and he died in 1926.[1]
