Thomas Henry FRS (26 October 1734 – 18 June 1816) was a surgeon and apothecary.

Henry was born in Wrexham, Wales training as a surgeon-apothecary in that town.

He was a founder and afterwards president of the Manchester Literary and Philosophical Society.

[4] In 1776, Thomas Henry speculated tongue in cheek that Joseph Priestley’s newly discovered dephlogisticated air (now called oxygen) might become “as fashionable as French wine at the fashionable taverns”.

He did not expect, however, that tavern goers would “relish calling for a bottle of Air, instead of Claret”.
