The Copley Medal is the most prestigious award of the Royal Society, conferred "for sustained, outstanding achievements in any field of science". It alternates between the physical sciences or mathematics and the biological sciences. Given annually, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". The medal is made of silver-gilt and awarded with a £25,000 prize.The Copley Medal is arguably the highest British award for scientific achievement, and has been included among the most distinguished international scientific awards. It is awarded to "senior scientists" irrespective of nationality, and nominations are considered over three nomination cycles. Since 2022, scientific teams or research groups are collectively eligible to receive the medal; that year, the research team which developed the Oxford–AstraZeneca COVID-19 vaccine became the first collective recipient. John Theophilus Desaguliers has won the medal the most often, winning three times, in 1734, 1736 and 1741. In 1976, Dorothy Hodgkin became the first female recipient; Jocelyn Bell Burnell, in 2021, became the second. Source: Wikipedia (en)
