The Bakerian Medal and Lecture is the premier lecture in physical sciences. The lectureship was established through a bequest by Henry Baker FRS (PDF) of £100 for 'an oration or discourse on such part of natural history or experimental philosophy, at such time and in such manner as the President and Council of the Society for the time being shall please to order and appoint'. The lecture series began in 1775. The medal is of silver gilt, is awarded annually and is accompanied by a gift of £10,000. https://royalsociety.org/grants-schemes-awards/awards/bakerian-lecture/
