John Smith (1798–1888) was an English botanist who was the first curator at Royal Botanic Gardens, Kew (Kew Gardens), starting in 1841. He had first been employed at the gardens as a stove boy (stoking stoves to warm the greenhouses) in 1822. Along with the directors, Sir William Jackson Hooker and Sir Joseph Hooker, he oversaw the conversion of the gardens from private royal gardens to public gardens when Queen Victoria converted them, possibly saving them from oblivion. He further prevented the gardens from catastrophic decline during the late 19th century when they were neglected in funding priorities. According to the Kew website, "It is significant that when stove-boy-Smith arrived at Kew, 40 species of fern were grown but when Curator Smith retired, there were 1,084."
