Samuel Hartlib or Hartlieb (c. 1600 – 10 March 1662)[1] was a Polish born, English educational and agricultural reformer of German-Polish origin[2] who settled, married and died in England. He was a son of George Hartlib, a Pole, and Elizabeth Langthon, a daughter of a rich English merchant.[3] Hartlib was a noted promoter and writer in fields that included science, medicine, agriculture, politics and education. He was a contemporary of Robert Boyle, whom he knew well, and a neighbour of Samuel Pepys in Axe Yard, London, in the early 1660s. He studied briefly at the University of Cambridge upon arriving in England.
