Career
He invented many fairy pieces and new conditions. He introduced the popular fairy pieces grasshopper, nightrider, and many other fairy chess ideas. Dawson published his first problem, a two-mover, in 1907.
His chess problem compositions include 5,320 fairies, 885 directmates, 97 selfmates, and 138 endings.
120 of his problems have been awarded prizes and 211 honorably mentioned or otherwise commended. He cooperated in chess composition with Charles Masson Fox.
He subsequently produced The Fairy Chess Review (1930-1951), which began as The Problemist Fairy Chess Supplement. At the same time he edited the problem pages of The British Chess Magazine (1931-1951).
Motivation and personality
According to The Oxford Companion to Chess:
His genius did not set him apart from his fellows.
He could find time for casual visitors, and would explain his ideas to a tyro with patience, modesty, and kindness. He composed less for fame than to amuse himself, confessing to another composer "We do these things for ourselves alone."

This problem is a strange case of incidence: thematic tourney prescript problems with grasshoppers without limiting number of the moves. The identical problem was sent independently by four composers.
