Frank Ludlow graduated from Cambridge in 1908 with a BA in natural sciences and on leaving university was appointed vice principal at Sind College, Karachi. During the First World War he served in Mesopotamia after which he went to Poona as Inspector of European Schools. In 1923 he opened a new school at Gyantse, Tibet. Although this closed in 1926 he remained on good terms with the Tibetan government and was almost uniquely allowed access to that country for a number of years. In 1927 he retired to Srinigar in Kashmir and from this date started travelling extensively, collecting birds and plants for the British Museum of Natural History. In 1928 he met George Sherriff in Kashgar in Chinese Turkestan and with their shared interests in ornithology, travel and plants they began a lifelong friendship which led to a series of major expeditions to the Eastern Himalayas and South East Tibet. During the 1930s they trekked through the Tian Shan mountains, Sikkim, Bhutan and Tibet, collecting thousands of plant specimens, though on these journeys Ludlow was more concerned with the collection of birds on which he wrote extensively. During the Second World War Ludlow was in charge of British Mission in Lhasa from 1942 to 1943 and was Joint Commissioner in Ladakh from 1940-42 and again from 1943-46. He continued collecting in 1946 setting off for South East Tibet again with Sherriff. Their sixth and final great expedition together was collecting alpine and temperate flora in Bhutan in 1949. They both returned to Britain in 1950 where Ludlow spent his remaining years working on their collections in the British Museum. Sources: R.
