Batt, born at Collingbourne, Wiltshire, on 18 June 1744, was for some time a student at Oxford University.
He then attended courses of medical instruction in the London schools, after which he went to Montpellier, where he took his doctor's degree in 1770.
[1] On completing his studies he returned to England, but on account of his health he subsequently removed to Genoa, where he obtained an extensive medical practice, and in 1774 was appointed professor of chemistry in the university.
Previous to this the study of chemistry in the university of Genoa had been much neglected, but soon after his appointment the lectures were thronged with pupils.
His wide and varied acquirements and his public spirit won him the general esteem of his fellow-citizens, which was greatly increased by his self-sacrificing attentions to the sick during the severe epidemic of 1800.
