In Memoriam Professor Geoffrey F. Hewitt

It is with great sadness that we share the news that Professor Geoffrey F. Hewitt, one of the co-founders of Hexxcell, passed away peacefully on Friday 18th January, aged 85, in the University College Hospital in London, surrounded by his family.

Professor Hewitt was a pioneer and recognised world leader in multi-phase flow and heat transfer with unparalleled achievements in these two fields. He was a Fellow of the Royal Society, the Royal Academy of Engineering, the Institution of Chemical Engineers where he served as President from 1989–1990, and a Foreign Associate of the US National Academy of Engineering.

For many decades, Professor Hewitt has represented the UK in a number of international professional bodies, including the Assembly for International Heat Transfer Conferences (of which he was Past President), EUROTHERM and the International Centre for Heat And Mass Transfer (of which he was a Vice-President). He also co-founded a number of prestigious publications (e.g. Heat Transfer Engineering, Heat Exchanger Design Handbook) and wrote several books dedicated to heat transfer, multi-phase flow and nuclear energy.

As impressive as his accolades were, what made exceptional for those who knew him personally was his unwavering optimism, his contagious passion for science and engineering, his curiosity for complex problems, his generosity and his refined manners. Professor Hewitt's legacy will continue through the many initiatives he started and championed over his long and prestigious career and through the large number of students, researchers and colleagues lucky enough to have had the opportunity to work with him.


Professor Hewitt’s funeral will be held on Tuesday 12th February at 12.00 noon at Golders Green Crematorium, West Chapel. Please RSVP if attending. Enquiries:
