Gerard John
Gerard, John, herbalist and surgeon, was born in 1545. After travelling, possibly as a ship's surgeon, he settled in London, superintending Lord Burleigh's gardens in the Strand and at Theobalds, and afterwards practising as a barber-surgeon and having a garden of his own. In 1597 he published his Herball, or yeneral historic of Plants, a translation of Dodoens' Pemptades (1583), which long remained a popular work, mainly owing to its revision in 1633 by Thomas Johnson. Gerard died in 1612.
