Alexander Macmillan Heron
Alexander Heron, geologist on the 1921 Everest Reconnaissance, was refused permission to join the 1922 expedition for having upset the Tibetans in 1921 by “disturbing demons in the ground.” Nevertheless, his work laid the foundations for later work by Odell (1924) and Wager (1933).
Heron was a graduate of Edinburgh University who joined the Geological Survey of India in 1906 and became its director from 1936 to 1939. During his long career, Heron spent 23 years conducting a geological survey of Rajasthan. He died aged 86 in the Nilgiri Hills of South India.
