Brookman was born 15 April 1850 in Glasgow, Scotland, the eldest son of typesetter Benjamin Brookman and his wife Jane née Wilson. The family emigrated to South Australia in 1852 on the Water Lily, arriving at Port Adelaide on 5 May and settled in Prospect. After completing his education at the schools of James Bath and E. C. Mitton, he found employment with grocery firm D & J Fowler. Then, with fellow-employee William Finlayson jun., he took over Fowler's retail arm in King William Street. He set himself up as a stock and share broker and earned a position in the Adelaide Stock Exchange in 1890. In 1893 he founded, with brother William Brookman and Sam Pearce, the Coolgardie Gold Mining and Prospecting Co. Ltd. syndicate which financed the exploration and proving of a mining lease "Ivanhoe" in Kalgoorlie, Western Australia, in what was later dubbed the "Golden Mile" and made its backers incredibly wealthy. The syndicate owed its success to dogged determination in the face of criticism from experts, as the mineral was in a form that had not been encountered before and through "Brookman's extraordinarily skilful financial transactions and able administration". He stood successfully for the Central District vacancy in South Australia's Legislative Council in 1901 caused by the resignation of Charles Kingston, who took up a seat in the new Federal Parliament. He was re-elected, but did not stand for the elections of 1910.
Business Activities
In 1896 he commissioned a four-storey block of offices "Brookman Building" at 35 Grenfell Street, Adelaide, previously the site of the Commercial Hotel. The architect was Alfred Wells.
He was involved with various patriotic movements, especially during the Great War: the State Repatriation Board, the Red Cross Society, the Anzac Hospitality Committee, and other organisations with similar aims.
Recognition
The large assembly hall of the School of Mines building, for which he contributed so generously, was named for him, as colloquially has the building itself.
He was knighted on 19 October 1920 for his "Services during the War" to the State, the Commonwealth, and the Empire.
