Timothy Clarke (died 1672) was an English physician, a founding Fellow of the Royal Society.
He enjoyed the favour of Charles II, before whom, as Samuel Pepys records, he conducted some dissections, ‘with which the king was highly pleased’.
On the death of Dr. Quartermaine in June 1667, Clarke was appointed second physician in ordinary to the king, with the reversion of Dr. George Bate's place as chief physician; and was named an elect of the College on 24 January 1670 in place of the late Sir Edward Alston.
[1] Clarke was one of the original Fellows of the Royal Society, and is named in the charter one of the first council.
He had also in preparation a work giving an account of his own original investigations in anatomy, which was to have been published at the expense of the Society, but this he did not live to complete.
