Summary

Robert Steele Dictionary of National Biography… (1912)

From 1854 till 1888, when he retired from Woolwich, Abel was the chief official authority on all matters connected with explosives. He was a member of the ordnance select committee, was expert for submarine defence and smokeless powder, and from 1888 until his death was president of the explosives committee. The transformation of arms and ammunition which took place during the thirty-four years of his service at Woolwich necessarily occupied the greater part of his scientific career, though almost every branch of technical science was enriched by his labours.

Although a divinity student, he was one of the earliest to engage in research work in the 'coalhole' in which Thomson had set up the first physical laboratory in Great Britain. After some time spent in teaching, Kerr was ordained a minister of the Free church, but did not take clerical duty. In 1857 he was appointed lecturer in mathematics to the Glasgow Free Church Training College for Teachers. This post he held for forty-four years, until his retirement in 1901. Here he set up a small laboratory, spending all his spare time in research.
