The New International Encyclopædia/Hartlib, Samuel
HART'LIB,  (c.1600-c.1670). An
English social reformer. He was born at Elbing,
West Prussia, of Polish ancestry, and went to
London in 1628. He is said to have introduced
the earlier writings of Comenius into England
(1637 and 1639), and to have taken an active
part in the movement for the unification of the

various Protestant sects. He was an intimate
friend of Milton, and is said to have been very
charitable. His publications, which are devoted
chiefly to educational and economic reforms,
include: Considerations Tending to the Happy
Accomplishment of England's Reformation in
Church and State (submitted to Parliament in
1647); Macaria (1641), containing the outlines
of an ideal State; and The Reformed Husbandman
(1651).
