Andrew David McLachlan explained

Andrew David McLachlan FRS^[1] (25 January 1935 – 8 July 2022) was a British scientist who worked in the areas of theoretical chemistry and molecular biology.

McLachlan studied mathematics at Cambridge^[2] before moving in to theoretical chemistry where his research was concerned with electron spin.^[3] Following time at Cambridge and Caltech, he made the move in to molecular biology at the MRC LMB in 1967.^[4] There he initially worked with Max Perutz on haemoglobin, before moving on to studying the sequence^[5] and structure^[6] of other protein types (such as muscle protein tropomyosin^{[7] [8]}). He retired in 2006.

McLachlan was elected Fellow of the Royal Society in 1989.^[2]
