Pontecorvo arranged his correspondence into folders of related material. This arrangement has been maintained. Folders of correspondence have been arranged below in a rough chronological order to show the development of Pontecorvo's ideas and research but kept within the original order within each folder. This is usually reverse chronological.

Biographical note

Guido Pellegrino Arrigo Pontecorvo (1907-1999), who liked to be known by his nickname, Ponte, was an Italian geneticist who became the University of Glasgow's first Professor of Genetics in 1955, and has been described as "one of the founding fathers of modern genetics". He endowed prizes and scholarships for students at the University and the Genetics Building was named for him in 1995. Born and educated in Pisa, Pontecorvo was forced to leave Italy in 1938 and settled in Scotland. He was appointed a lecturer in Genetics at the University's Zoology Department in 1945, and a new department was set up in the Anatomy laboratories of the Anderson College building soon afterwards. He became a Reader in 1952, three years before his appointment to the new Chair. He left Glasgow in 1968 to take a post at the Imperial Cancer Research Fund's laboratories in London. Pontecorvo was one of the leading figures of his day in the study of of cell genetics. For a more detailed biography see the full Pontecorvo collection description.

Pontecorvo's earlier research was concerned with animal breeding and radiation effects and genetics of speciation with Drosophila. He made significant contributions to cattle breeding in Tuscany where he organized a wide-ranging programme of recording and selective breeding for milk yield and draught ability in two regional cattle breeds. When he came to Glasgow Pontecorvo's main interests were in mitotic genetics, mutation theories, gene regulation and recombination and what Pontecorvo himself liked to call "Parasexual cycle genetics". Pontecorvo's two main contributions to genetics were his discovery of the parasexual cycle in fungi, which led him to develop methods of genetics analysis that became the foundations of what is now known as somatic cell genetics. The Parasexual Cycle was successfully patented in 1954 and was the first patent to be issued in any jurisdiction for a natural biological process. Pontecorvo's second major contribution to genetics was his work on intragenic recombination and his seminal paper titled 'Genetic formulation of gene structure and gene action' (1952), on the organisation of the genetic material. This paper proposed a new theory of the gene a year before Watson and Crick's famous discovery of the structure of DNA.
