About
Lewis Wolpert (19 October 1929 – 28 January 2021) was a South African-born British developmental biologist, author, and broadcaster. Wolpert popularized his French flag model of embryonic development, using the colours of the French flag as a visual aid to explain how embryonic cells interpret genetic code for expressing characteristics of living organisms and explaining how signalling between cells early in morphogenesis could inform cells with the same genetic regulatory network of their position and role.
