Jean-Baptiste was born in 1746 in
Lons-le-Saunier, France, where he worked as a
tanner. In 1771 after being successfully treated for
scrofula (
tuberculosis of the neck) at
Bicêtre Hospital, Pussin was recruited as a member of the hospital staff. In 1784 he attained the position of superintendent of the mental ward, and from 1786 was assisted there by his wife Marguerite. Pussin advocated a relatively humane treatment, engaged in psychologically-based work with patients, and maintained records regarding his empirical observations and therapeutic proposals. In 1793 he was visited at the Bicêtre by physician
Philippe Pinel (1745-1826), who had just started work at the hospital. Pinel was impressed by Pussin's approach and the positive results he had achieved. In 1797, after Pinel had left, Pussin instituted a reform that permanently banned the use of all chains to restrain patients. Straitjackets continued to be used, however. Not long after Pinel was assigned to the
Salpêtrière Hospital, he arranged to have Pussin move there with him, as a special assistant. Chains were then banned there also. In 1801 Pinel published his
Treatise on Insanity, which describes their work. In 1809, in the second edition of the
Treatise on Insanity, Pinel reports Pussin’s initiative to ban the use of chains. Jean Baptiste Pussin died in 1811. ==Clinical approach==
