Life

Linstead studied chemistry from 1920 at Imperial College London , where he received his doctorate in 1926 under George Armand Robert Kon and was then assistant. From 1928 to 1929 he worked for the Anglo-Persian Oil Company and then again at Imperial College. In 1930 he received a D.Sc. from the University of London . In 1938 he became professor of chemistry at the University of Sheffield and in 1939 professor of organic chemistry at Harvard University . In 1942 he was back in England as Deputy Research Director at the Ministry of Supply , doing research on explosives and metals. In 1945 he became director of the Chemical Research Laboratory in Teddington. In 1949 he became a professor of organic chemistry at Imperial College London, whose rector he became.

Linstead was a pioneer in researching phthalocyanine dyes. The starting point was a batch from the phthalimide production of an ICI plant in Scotland , in which a dark blue substance had formed on contact with iron, which was handed over to Imperial College for investigation. Linstead was able to reproduce this in the laboratory and suspected a structure similar to porphyrin (1933), which was confirmed by X-ray structure studies .

In 1954 he turned to chlorophyll and was able to supplement Hans Fischer's structural analysis .

From 1940 he was a Fellow of the Royal Society and Commander of the Order of the British Empire (CBE). In 1959 he was knighted as a Knight Bachelor . The Linstead Hall at Imperial College was named in his honor.
