Vice-Chancellor and Principal聽Dr Michael Spence AC聽paid tribute to the late Lord Robert May 鈥� a champion for science who was dubbed one of the fathers of chaos theory: 鈥淟ord Robert May鈥檚 contribution to chaos theory has helped us better understand the reproduction of disease and pandemic management 鈥� something unequivocally invaluable in the global fight against COVID-19. His life-time dedication to scientific inquiry and his desire to see the world flourish through the lens of mathematics embodies the Sydney spirit.鈥�

鈥淲e are incredibly honoured to call him one of our own.鈥�

Early career and time at Sydney

Born and raised in Sydney, Lord Robert May 鈥� affectionately known by most as 鈥楤ob鈥�, graduated from a Bachelor of Science with the University Medal in Physics at the University of Sydney in 1957. He also completed a PhD in theoretical physics in 1960 under the supervision of Robbie Schafroth, working alongside renowned physicist and educator聽Harry Messel, who was then heading up the聽School of Physics. Lord Robert May recounted in an interview聽Sydney Alumni Magazine聽(SAM) in 2008 that the reason he chose theoretical physics was because 鈥淗arry and his mates鈥� looked like they were having a lot of fun.

Later on, Lord Robert May was known for his metamorphosis into biology through his mathematical investigation of the relation between stability and complexity in natural communities.

During his time at the University of Sydney, 鈥楤ob鈥� was an avid chess and snooker player. 鈥淚 spent roughly half my university years playing chess or snooker in the union and just having a good time. I did not do my second-year laboratory chemistry very conscientiously, because it was too time consuming. I used various tricks and devices to abbreviate the time, which I think required more scientific insight than actually doing it honestly,鈥� he said in an interview with the聽聽in 2008.

Lord Robert May was a brilliant debater in high school and revisited his love for debating at the University:

鈥淚n my second year of graduate school, in 1958, I thought, 鈥榃hat the hell. Just for a lark, I鈥檒l try out for the Sydney University team鈥�. Not only did I make the team but we won intervarsity,鈥� he said in the same interview.

Throughout his career, Lord Robert May taught at the University of Sydney for 10 years as a Professor of Theoretical Physics and in various positions at Harvard University, Princeton University and Oxford University before becoming the Chief Scientific Advisor to the UK government in 1995.

Remembering Lord Robert May鈥檚 achievements

Lord Robert May was awarded a Doctor of Science (honoris causa) by the University in 1995 for his significant contribution to science. The then Vice-Chancellor and Principal Professor Donald McNicol said, 鈥淧rofessor May has a record of outstanding achievement in two very different fields of science - theoretical physics and population biology.鈥�

A knight, lord, baron, professor, president and chief advisor, Lord Robert May鈥檚 countless awards and achievements include his appointment as a Companion of the Order of Australia in 1998.

Despite his many titles and impressive accolades, Lord Robert May remained a true Aussie through-and-through, he was most notably known as the first person to record a swear word in聽鈥檚 minutes.

Lord Robert May鈥檚 contributions to science

Lord Robert May introduced a logistic process to describe the dynamics of insect populations, which led to chaos theory. Chaos theory is a branch of mathematics that states a simple, seemingly random chaotic system can have patterns and repetition. Combining mathematics and biology 鈥� Lord Robert May translated complex ecological processes into simple mathematics.

A world-leading theoretical population biologist, Lord Robert May used scientific research as a vehicle to solve pressing social concerns. A man with a true heart for humanity, he applied his work to everything from ecological systems, stability of banking systems during the GFC in 2008 to the epidemiology of AIDS and infectious disease control.

His work on the basic聽聽and disease modelling methods have been key in the current global effort to control COVID-19.

Lord Robert May鈥檚 zeal for science and curiosity led to an incredibly accomplished career and life 鈥� but always with great humour and humility. When asked why he chose a career in science in an interview with聽Sydney Alumni Magazine聽(SAM), Lord Robert May recounted that it was equal parts defiance (careers advisors and family preferred medicine or law), practicality, and, to a boy who could top classes he didn鈥檛 study for 鈥� a 鈥渇un鈥� game to sit the same exams as his friends.

Lord Robert May sadly passed away on 28 April 2020 at the age of 84.
