Jim Danielli, who was my supervisor and who allowed me to come and do a PhD in his... in his department... Jim Danielli’s great achievement was working out the structure of the membrane that surround cell, and what... he was the one that showed very clearly that it was made of both of proteins and lipids, and it was a bi-molecular lipid layer surrounded by protein that was the basic structure of the membrane, and that was absolutely fundamental to understanding membrane structure, and membranes determine what can get into the cell and what can get out of the cell, and my friend, Wilfred Stein, the one who got me into biology, what he worked on was permeability — how molecules got in and out of cells.

Lewis Wolpert (1929-2021) CBE FRS FRSL was a developmental biologist, author, and broadcaster. He was educated at the University of Witwatersrand (BSc), Imperial College London, and at King's College London (PhD). He was Emeritus Professor of Biology as applied to medicine in the Department of Anatomy and Developmental Biology at University College London. In addition to his scientific and research publications, he wrote about his own experience of clinical depression in Malignant Sadness: The Anatomy of Depression (1999).
