Bolus was born in Nottingham, England. He was educated at Castle Gate School, Nottingham. The headmaster George Herbert regularly corresponded with and received plant specimens from William Kensit of Grahamstown, South Africa. Kensit requested that the headmaster send him one of his pupils as an assistant; Harry Bolus duly landed at Port Elizabeth from the ship Jane in March 1850. He spent two years with Kensit and then moved to Port Elizabeth. Following a short visit to England, he settled in Graaff-Reinet, where he would live for the next 19 years. In 1857 he married Sophia Kensit, the sister of William Kensit. Between 1858 and 1870 they had 3 sons and a daughter. In 1864 he lost his eldest son of six years, and Francis Guthrie who had become a close friend, suggested his taking up botany to ameliorate his loss. He started his botanical collection in 1865 and was soon corresponding with Joseph Hooker at Kew, William Henry Harvey in Dublin and Peter MacOwan in Grahamstown. One of his most treasured gifts was a copy of De Candolle's Prodromus received from Guthrie in 1869. In 1875, he joined his brother Walter in Cape Town, settling in the suburb of Kenilworth, where they founded a stockbroking firm called Bolus Bros. The following year he and Guthrie made their first visit to Kew, taking with them a large number of plant specimens for naming. Bolus described the period as 'forty happy days'. Returning in the Windsor Castle in October 1876, the ship struck a reef off Dassen Island with the loss of his specimens and notes. Not daunted, he set about the collection of new specimens and organised expeditions to various corners of South Africa. He was an excellent field botanist and published numerous books on his observations. Although adventurous by nature, he was also quiet and unassuming. His business flourished so he was able to acquire many fine botanical books. Complete sets of the Botanical Magazine, Botanical Register, Refugium Botanicum, and the large folios of Pierre-Joseph Redouté, Nikolaus Joseph von Jacquin, Ferdinand Bauer and Francis Masson formed part of his collection. He founded the Harry Bolus Professorship at the University of Cape Town and left a large trust for scholarships. He also donated his extensive herbarium and library to the South African College. He was one of the founding Members of the South African Philosophical Society. Harry Bolus loved visiting England and made a total of 28 voyages to and from South Africa. He died of heart failure at Oxted, Surrey, on 25 May 1911. His youngest son Frank married Harriet Margaret Louisa Kensit, William Kensit's granddaughter, the following year.
