The Society regrets to hear of the death of Honorary Member Sir John Sulston CH who was awarded the Nobel Prize for Physiology or Medicine in 2002 for his work on cell lineages and on the first complete DNA sequence to be published, of the nematode worm Caenorhaditis elegans. A forceful advocate for genome information remaining in the public domain, he became the founding director of the Wellcome Sanger Centre at Hinxton. In 2002, he gave The Society’s Annual Review Prize Lecture on the ethical uses of science.
