Alistair recruited me as Leatherhead's research director in 2005. At my interview his gravitas, sharp mind and knowledge of the food industry instantly impressed me. He later told me about his illustrious career at Unilever, spanning nearly 35 years, ending with a tenure as director of Unilever's Colworth research laboratory. Often when we discussed 'new' research ideas it emerged he had done similar work years ago at Unilever.
In 1969, after gaining a PhD from Edinburgh University, he became a carbohydrate chemist at Unilever. He worked his way up via successful posts at Batchelors, Brooke Bond and Unilever.
He championed the creation of a new Diet and Health Research Industry Club (DRINC) on the Biotechnology and Biological Sciences Research Council. I worked with him on the Club's steering group, which he chaired. Under his guidance DRINC funded exceptional diet and health projects.
Alistair's career included four years as chairman of the Governing Body of the Institute of Food Research. He was also Board Trustee of East Malling Horticultural Research Institute.
He was an expert in carbohydrate chemistry, directing Unilever research on tea ingredients, especially bioactives, some of it way ahead of its time. Studies on green and black tea's health benefits continue. I only recently learned that he was an honorary Professor of the Tea Research Institute in Hangzhou, China.
Under his leadership, Leatherhead thrived. An excellent mentor, he named me chief executive in 2008. I will miss his wisdom, scientific expertise and sense of humour. The food industry has lost a great champion.
My deepest sympathy is extended to his wife, Gina, and his family.
Paul Berryman is chief executive at Leatherhead Food Research.
