SCHOMBERG, ISAAC (1714–1780), physician, younger son of Dr. Meyer Löw Schomberg [q. v.] and twin-brother of Raphael or Ralph Schomberg [q. v.], was born at Schweinberg on 14 Aug. 1714. He was entered at Merchant Taylors' School, London, in 1726, and at an early age, under the auspices of his father, commenced practising medicine in London. He had no English degree, and in February 1746–7 he was summoned before the president and censors of the College of Physicians to present himself for examination as a licentiate, but declined the invitation in a letter which was officially termed ‘improbable and indecent.’ In the early part of 1747 he was entered at Trinity College, Cambridge, and on 7 Aug. 1747, when a ‘student at physic of Trinity College, Cambridge,’ he was baptised at St. Mary Woolnoth, London (Registers, ed. Brooke and Hallen, p. 111). On 3 April 1747 he notified the former fact to the censors, with a request that he might be examined after he had procured his medical degree from that university. This request was refused, and, as he still declined to be examined, his practice was interdicted by the Comitia minora of the College of Physicians on 25 June 1747.
Schomberg obtained on 21 July 1749 by royal mandate the degree of M.D. at Cambridge, and thereupon, in order that he might become a candidate for admission to the College of Physicians, claimed his examination; but the censors were ordered by the college not to examine him until his prohibition from practice had been removed on proper submission. On the following 1 Dec. he again came before the censors, and on
