Deering was born in Saxony, educated at Hamburg and Leyden, and came to London in 1713 as secretary to Baron Schach, envoy to Queen Anne from Peter the Great.
He remained in England as a tutor till November 1718, when he married and returned to the continent, where he took a degree at Reims, 13 December 1718.
[2] He joined the botanical society set up by Johann Jakob Dillenius and John Martyn, which existed from 1721 to 1726.
At first Deering was successful in his practice, and issued a short tract on his method of treating the small-pox; but he may have been temperamentally unsuited to the work, He was made ensign in 29 October 1745, in the Nottingham infantry regiment, during the 1745 Jacobite Rebellion.
[1] Materials collected by John Plumptre (died 1751) for a history of Nottingham were passed to Deering by friends.
