Biography

Born in Bachelor of Arts degree in chemistry with first class honours from the University of Oxford in 1949. In 1950 he was elected a Fellow of Magdalen College, Oxford and in 1951 was awarded his Ph.D in chemistry at Oxford.

Orgel started his career as a California Institute of Technology and the University of Chicago.

Together with Salk Institute for Biological Studies.[3]

In 1955 he joined the chemistry department at Cambridge University. There he did work in transition metal chemistry, published articles and wrote a textbook entitled Transition Metal Chemistry: Ligand Field Theory (1960).

In 1964, Orgel was appointed Senior Fellow and Research Professor at the Viking Mars Lander Program as a member of the Molecular Analysis Team that designed the gas chromatography mass spectrometer instrument that robots took to the planet Mars.

Orgel’s lab came across an economical way to make cytarabine, a compound that is one of today’s most commonly used anti-cancer agents.

During the 1970s, Orgel suggested reconsidering the Panspermia hypothesis, according to which the earliest forms of life on earth did not originate here, but arrived from outer space with meteorites.

Together with peptide nucleic acids - rather than ribonucleic acids - constituted the first pre-biotic systems capable of self-replication on early Earth.

His name is popularly known because of Evolution is cleverer than you are".

In his book The Origins of Life, Orgel coined the concept of specified complexity, to describe the criterion by which living organisms are distinguished from non-living matter. He published over three hundred articles in his research areas.

Orgel died of cancer on 27 October 2007 at the San Diego Hospice & Palliative Care in San Diego, California.
