The Croonian Medal and Lecture 2023 is awarded to Professor Dame Ottoline Leyser DBE FRS for playing a central role in two of the most important discoveries regarding the nature and perception of plant hormones, and for her contributions to gender equality in science.

The award

The Croonian Medal and Lecture is the premier lecture in the biological sciences. The lectureship was conceived by William Croone FRS (PDF), one of the original Fellows of the Society. Among the papers left on his death in 1684 were plans to endow two lectureships, one at the Royal Society and the other at the Royal College of Physicians. His widow later bequeathed the means to carry out the scheme. The lecture series began in 1738. The medal is of silver gilt, is awarded annually and is accompanied by a gift of £10,000. 


The Croonian medal and lecture is open to international citizens. It is restricted to senior scientists and nominations will remain valid and shall be considered by the award selection committee throughout three nomination cycles. Teams or groups may now be nominated for this award.


Nominations for this award will open in November 2023.
