Bill A. Walker

Bill A. Walker (29 August 1886 – 8 November 1934) was an Australian rules footballer who played for Essendon in the VFL.

Walker, also known by his nickname 'Johnnie', was recruited from the Collingwood Juniors. A ruckman, he was a member of Essendon's 1911 and 1912 premiership teams. His 14 goals in 1915 was enough to top Essendon's goal-kicking.

Alick Donald Walker (26 October 1925 – 4 December 1999) was a British palaeontologist, after whom the Alwalkeria genus of dinosaur is named.

He was born in Skirpenbeck, near York and attended Pocklington School from 1936 to 1943. He began a degree course in engineering at Cambridge, but dropped out in 1944. In 1948 he returned to university after national service, reading Geology at the University of Bristol. On graduation, he join the research group of Professor Stanley Westoll at the University of Newcastle upon Tyne, working on the fossil reptiles of the Late Triassic found in Elgin. He was appointed Lecturer in Geology in 1954, while working on his PhD.

The bony remains of the Elgin reptile fossils were poor, sometimes just indentations in rocks. Walker devised a new casting method to capture the anatomical information in these fossils, using PVC; many of the resulting casts are now in the National Museum of Scotland and the Natural History Museum. His early work was also notable for reclassifying and naming Eustreptospondylus.
