“Saddened to hear of the passing of Prof Calestous Juma. We have lost a brilliant mind who was dedicated to innovation, education and Africa’s prosperity. Condolences to his family and friends. May he rest in peace,” reads the Head of State’s tweet.
Others who expressed their condolences include, the Minister of Foreign Affairs and East African Community Affairs, Louise Mushikiwabo who said that Africa has lost a very important African who was always striving to serve the continent.
“Calestous was a very valuable African, always wanting his brilliant mind to serve the continent! May his family and Havard colleagues find in his life strength and solace!” reads the Minister’s tweet.
According to Daily Nation, Calestous was unwell for the past two years.
“Prof has been unwell for the past two years and today we received the sad news of his passing. Any more details will come from his family,” Calestous lawyer, Peter Wanyama told Daily Nation yesterday.
According to Daily Nation, in 2012, 2013 and 2014 Calestous had been listed among the most influential 100 Africans by the New African magazine.
He began his career as a science teacher in Mombasa between 1974 and 1978 before becoming the first science and environment journalist for Daily Nation between 1978 and 1979.
He later started his own magazine, Ecoforum.
It was during his brief stint at the Nation that environmental issues were prominently covered by Kenyan media.
He later worked as an editor and researcher at the Environment Liaison Centre in Nairobi between 1979 and 1982.
The scientist, who attained a teacher’s certificate from Egoji Teacher’s College in 1974, also held a PhD in Science Policy Research from the University of Sussex.
At the time of his death, he was teaching graduate courses on science, technology and development policy and biotechnology at Harvard University.
