President of the Royal Society in the context of "Humphry Davy"

William Thomson, 1st Baron Kelvin (26 June 1824 – 17 December 1907), was a British mathematician, mathematical physicist and engineer. Born in Belfast, he was for 53 years the professor of Natural Philosophy at the University of Glasgow, where he undertook significant research on the mathematical analysis of electricity, was instrumental in the formulation of the first and second laws of thermodynamics, and contributed significantly to unifying physics, which was then in its infancy of development as an emerging academic discipline. He received the Royal Society's Copley Medal in 1883 and served as its president from 1890 to 1895. In 1892 he became the first scientist to be elevated to the House of Lords.

Absolute temperatures are stated in units of kelvin in Lord Kelvin's honour. While the existence of a coldest possible temperature, absolute zero, was known before his work, Kelvin determined its correct value as approximately −273.15 degrees Celsius or −459.67 degrees Fahrenheit. The Joule–Thomson effect is also named in his honour.

Venkatraman Ramakrishnan (born 1952) is a British-American structural biologist. He shared the 2009 Nobel Prize in Chemistry with Thomas A. Steitz and Ada Yonath for research on the structure and function of ribosomes.

Since 1999, he has worked as a group leader at the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) on the Cambridge Biomedical Campus, UK and is a Fellow of Trinity College, Cambridge. He served as President of the Royal Society from 2015 to 2020.

Sir Paul Maxime Nurse (born 25 January 1949) is an English geneticist, President of the Royal Society and former Chief Executive and Director of the Francis Crick Institute. He was awarded the 2001 Nobel Prize in Physiology or Medicine, along with Leland Hartwell and Tim Hunt, for their discoveries of protein molecules that control the division of cells in the cell cycle.
