On day 225 of #LMB365 is Fred Sanger who was born #OTD in 1918. He is the only Briton to have been awarded two @Nobel prizes and the only scientist to have been awarded the Nobel Prize for Chemistry twice: in 1958 and 1980. He first developed methods for amino acid sequencing and then pioneered a technique to sequence nucleic acids, the building blocks in DNA. This method would shape the way that genomics and biomedicine were explored and was key to the Human Genome Project
