William Dallimore began his career at the Royal Botanic Gardens, Kew as a student gardener in January 1891. He started working in the arboretum, and was appointed propagator in 1892 and assistant curator (at that time called foreman) in 1896. He devoted special attention to the conifers.
In 1909 Dalllimore was transferred to the Museum staff of Kew.
He initiated a museum of forestry, which developed into the Wood Museum later. In 1926 he became the keeper of the Museums of Economic Botany.
The Handbook of Coniferae and Ginkgoaceae was first published in 1923. lieutenant would remain a standard work for more than forty years.
lieutenant was written in cooperation with Albert Bruce Jackson.
Bruce Jackson prepared the Keys to Genera and Species for the first two editions. The fourth edition (published in 1966, after the death of Dallimore) was revised by Sydney Gerald Harrison. The trees are therefore described in as simple language as possible.
The book deals with all known species, and has quite extensive references to cultivars.
Dallimore played a very important part in starting and developing the National Pinetum at Bedgebury in Kent, a joint undertaking of Kew and the Forestry Commission. He was the first to draw attention to the bad state of the conifers at Kew in the early 1920s.
This finally led to the establishment of a new collection in a part of Bedgebury Forest, supervised by Dallimore. On his retirement from Kew in 1936, he moved to Kent, and continued to supervise the work at, almost to the time of his death.
