Khartoum — A shadow of grief over the weekend clouded the Sudanese websites and social media over the stunning and untimely departure of Mathematician, Prof. Salah-Eldin Mohammed Ahmed who died in the American city of Carbondale, where he taught and researched at the Department of Mathematics, Southern Illinois University.
The late professor was born in the town of Rufa'a (Gezira State of Central Sudan) and grew up between Rufa'a and Khartoum.
He obtained his first degree in mathematics from the University of Khartoum (First Class with Distinction) in 1970. Then he very swiftly climbed the ladder of excellence, obtaining his M.Sc (with Distinction) from the University of Dundee, Scotland, in 1972 and his PhD from the University of Warwick, Coventry, England in 1976.He then continued his journey of excellence, teaching and researching in several universities and institutions in the West.
Throughout his successful scientific career, Prof. Ahmad had received a lot of honors, awards and titles.
Among these were the celebrated title of Distinguished Scholar, SIU-C (2006) from the University of Carbondale, the SIU -C Outstanding Scholar (2006) and SIU-C College of Science Outstanding Researcher (2005), etc.
In an obituary, the Sudanese Community in the City of Carbondale said it was extending its " deep condolences to the family of the deceased that was always hospitable and welcoming of the Sudanese who happened to pass through the City of Carbondale."
"The home of Prof. Ahmad and his family was but a shady tree under which every visitor to Carbondale had rested to the care of Prof. Ahmad and his wife," said the Community.
"Further, Prof. Ahmad and his family were always ready with celebrations for the graduation of Sudanese students from the University of Carbondale .May Allah, the Almighty, console his family and may He rest his noble soul in eternal peace," it said.
Wrote Dr.Zuhair al-Sarraj, a columnist and University Professor of Veterinary: "Prof. Ahmad had obtained the title of distinguished academic in 2007 from the University of Carbondale, a title that gave him precedence over all the University's staff in that year."
"That is not just a title. It is a respectful title that derives its fame and respect from the pane that awards it and the protracted procedures that precede it."
Prof. Ahmad Mohammad Ahmad is survived by his wife Salwa al-Jizouli and his two offspring: Yasar and Dr. Hassan.
