Fred Sanger on Working with Alan Coulson
  Fred Sanger     Biography    
Recorded: 16 Jun 2005

He was a colleague who worked with me. I think my two favorite technical assistants was Bart Barrell who was the first one who did a lot of the early work, and helped me very much with the protein stuff and Alan Coulson. He was my main collaborator in the lab, we worked together really, very skillful technologists, both of them. There were other technicians, too. I would say that Bart Barrell and Alan Coulson were my chief colleagues really and helpers with the work. I like to work at the lab myself and do the experiments which most sort of senior scientists don’t do very much now. But to me that was the fun of it. I think that’s one of the reasons why I retired probably when I was 65. That the subject got so complicated and so big that you didn’t need an expert to do the experiments really. I would have had to talk and sit in an office and use a computer or something.

Frederick Sanger, OM, CH, CBE, FRS (born 13 August 1918) is an English biochemist and twice a Nobel laureate in chemistry. In 1958 he was awarded a Nobel prize in chemistry "for his work on the structure of proteins, especially that of insulin". In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids". The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant-DNA".

He is the fourth (and only living) person to have been awarded two Nobel Prizes, either wholly or in part.
