Harold Ramkissoon. Harold Ramkissoon (14 April 1942 – 15 November 2024) was a Trinidadian mathematician, academic, and science advocate known for his work in fluid dynamics. He served as Professor Emeritus of Mathematics at the University of the West Indies, and was an independent senator of the Parliament of Trinidad and Tobago.

Early life and education 
Harold Ramkissoon was born on 14 April 1942, in Tabaquite, Trinidad, and grew up in Marabella. He attended Tabaquite RC Primary School and later Presentation College. In 1966, he earned a Bachelor of Science degree in mathematics from the University of the West Indies (UWI). He completed a Master of Science in Mathematics at the University of Toronto in 1969 and a Ph.D. in applied mathematics at the University of Calgary in 1975. His doctoral research focused on fluid dynamics, including micropolar fluids, and marangoni instabilities.

In 2019, Ramkissoon received an honorary doctorate from the University of the West Indies and the Faculty of Science and Technology’s Lifetime Achievement Award.

Career 
Ramkissoon joined the University of the West Indies in 1976 as a lecturer in mathematics. He was promoted to senior lecturer in 1982, reader in mathematics in 1990, and, in 1998, became the first West Indian to be appointed to a personal chair in mathematics at UWI. He retired in 2007 and was named professor emeritus.

He collaborated with institutions such as Cambridge University, the Massachusetts Institute of Technology, Princeton University, and the Chinese Academy of Sciences. Ramkissoon authored over 85 peer-reviewed research papers and contributed to five books in applied mathematics.

Ramkissoon worked to advance science and technology in the Caribbean. He led the Caribbean Academy of Sciences (1994–1998) and the Caribbean Scientific Union (2002–2004). He founded the Caribbean Congress of Fluid Dynamics and chaired regional scientific conferences. In 2014, Ramkissoon was appointed Chair of the CARICOM Science and Technology (S&T) Committee, launched by Prime Minister Keith Mitchell of Grenada. From 2010 to 2013, he served as an independent senator in the Parliament of Trinidad and Tobago, advocating for policies supporting research and development. He also established the Trinidad and Tobago National Mathematics Olympiad to promote interest in mathematics and science among young people.

In 2017, Harold Ramkissoon launched his autobiography, My Journey, in Trinidad and then in Guyana through events organized by the University of the West Indies, the University of Guyana and the Ministry of Education.

Ramkissoon was a founding member and president of the Caribbean Academy of Sciences. He held executive roles in organizations such as the InterAcademy Partnership and the Academy of Sciences for the Developing World (TWAS). He participated in the Pugwash Conferences on Science and World Affairs, which received the Nobel Peace Prize in 1995, and was a fellow of the European Academy of Sciences and Arts. He was also a corresponding member of science academies in Cuba and Venezuela.

Death and tributes 
Ramkissoon died on 15 November 2024, at the age of 82. The Office of the President of Trinidad and Tobago and the Parliament of Trinidad and Tobago acknowledged his contributions and achievements on 26 November.

Awards and recognition 
Ramkissoon received several awards for his contributions to education, including the Chaconia Gold Medal in 2000, the Simón Bolívar Academic Gold Medal in 2001, and the Caricom Science Award in 2006. He was awarded honorary Doctor of Science degrees from the University of Technology, Jamaica, in 2011, and the University of the West Indies, St. Augustine, in 2019.

Ramkissoon was a recipient of fellowships from the Alexander von Humboldt Foundation and the Fulbright Foundation, and he was inducted into the CARISCIENCE Hall of Fame in 2015.
