Sir John Edward Sulston CH FRS MAE (27 March 1942 – 6 March 2018) was a British biologist and academic who won the Nobel Prize in Physiology or Medicine for his work on the cell lineage and genome of the worm Caenorhabditis elegans in 2002 with his colleagues Sydney Brenner and Robert Horvitz. He was a leader in human genome research and Chair of the Institute for Science, Ethics and Innovation at the University of Manchester. Sulston was in favour of science in the public interest, such as free public access of scientific information and against the patenting of genes and the privatisation of genetic technologies.

Early life and education

Sulston was born in Fulmer, Buckinghamshire, England to Arthur Edward Aubrey Sulston and Josephine Muriel Frearson, née Blocksidge. His father was an Anglican priest and administrator of the Society for the Propagation of the Gospel. His mother quit her job as an English teacher at Watford Grammar School, to care for him and his sister Madeleine. and home-tutored them until he was five. At age five he entered the local preparatory school, York House School, where he soon developed an aversion to games. He developed an early interest in science, having fun with dissecting animals and sectioning plants to observe their structure and function. Sulston won a scholarship to Merchant Taylors' School, Northwood and then to Pembroke College, Cambridge graduating in 1963 with a Bachelor of Arts degree in Natural Sciences (Chemistry). He joined the Department of Chemistry, University of Cambridge, after being interviewed by Alexander Todd and was awarded his PhD in 1966 for research in nucleotide chemistry.


Between 1966 and 1969 he worked as a postdoctoral researcher at the Salk Institute for Biological Studies in La Jolla, California. His academic advisor Colin Reese had arranged for him to work with Leslie Orgel, who would turn his scientific career onto a different pathway. Orgel introduced him to Francis Crick and Sydney Brenner, who worked in Cambridge. He became inclined to biological research.

Although Orgel wanted Sulston to remain with him, Sydney Brenner persuaded Sulston to return to Cambridge to work on the neurobiology of Caenorhabditis elegans at the Medical Research Council (MRC) Laboratory of Molecular Biology (LMB). Sulston soon produced the complete map of the worm's neurons. He continued work on its DNA and subsequently the whole genome sequencing. In 1998, the whole genome sequence was published in collaboration with the Genome Institute at Washington University in St. Louis, so that C. elegans became the first animal to have its complete genome sequenced.

Sulston played a central role in both the C. elegans and human genome sequencing projects. He had argued successfully for the sequencing of C. elegans to show that large-scale genome sequencing projects were feasible. As sequencing of the worm genome proceeded, the Human Genome Project began. At this point he was made director of the newly established Sanger Centre (named after Fred Sanger), located in Cambridgeshire, England.

In 2000, after the 'working draft' of the human genome sequence was completed, Sulston retired from directing the Sanger Centre. With Georgina Ferry, he narrated his research career leading to the human genome sequence in The Common Thread: A Story of Science, Politics, Ethics, and the Human Genome (2002).

Awards and honours

Sulston was elected a Fellow of the Royal Society (FRS) in 1986. He was elected an EMBO Member in 1989 and awarded the George W. Beadle Award in 2000. In 2001 Sulston gave the Royal Institution Christmas Lectures on The Secrets of Life. In 2002, he won the Dan David Prize and the Robert Burns Humanitarian Award. Later, he shared the Nobel Prize in Physiology or Medicine with Sydney Brenner and Robert Horvitz, both of whom he had collaborated with at the MRC Laboratory of Molecular Biology (LMB), for their discoveries concerning 'genetic regulation of organ development and programmed cell death'. One of Sulston's most important contributions during his research years at the LMB was to elucidate the precise order in which cells in C. elegans divide. In fact, he and his team succeeded in tracing the nematode's entire embryonic cell lineage.

In 2004, Sulston received the Golden Plate Award of the American Academy of Achievement. In 2006, he was awarded the George Dawson Prize in Genetics by Trinity College Dublin. In 2013, Sulston was awarded the Royal Society of New Zealand's Rutherford Memorial Lecture, which he gave on the subject of population pressure.

He was appointed a Member of the Order of the Companions of Honour (CH) in the 2017 Birthday Honours for services to science and society.

On 23 October 2017 he was awarded the Cambridge Chemistry Alumni Medal.

Sulston was a leading campaigner against the patenting of human genetic information.

Personal life

The Sulston Laboratories of the Wellcome Trust Sanger Institute are named in Sulston's honour.

John Sulston met Daphne Bate, a research assistant in Cambridge. They got married in 1966 just before they left for US for postdoctoral research. Together they had two children. Their first child, Ingrid, was born in La Jolla in 1967, and their second, Adrian, later in England. The couple lived in Stapleford, Cambridgeshire where they were active members of the local community: John regularly volunteered in the local library and in working parties at Magog Down; he was a Trustee of Cambridge Past, Present and Future.

Although brought up in a Christian family, Sulston lost his faith during his student life at Cambridge, and remained an atheist. He was a distinguished supporter of Humanists UK. In 2003 he was one of 22 Nobel Laureates who signed the Humanist Manifesto.

Sulston was in favour of free public access of scientific information. He wanted genome information freely available, and he described as "totally immoral and disgusting" the idea of profiteering from such research. .....

In December 2010, Sulston backed Julian Assange by acting as a bail surety for him, according to Assange's attorney Mark Stephens. Sulston forfeited £15,000 of the £20,000 pledged in June 2012, as Assange had entered the embassy of Ecuador to escape the jurisdiction of the English courts.

Sulston died on 6 March 2018 of stomach cancer, aged 75 years.
