Humphry William Woolrych (1795-1871) was an English barrister, who was admitted to Gray's Inn in 1847 and made a Serjeant-at-Law in 1855. He was a prolific writer of law books including the two volume "Lives of Eminent Serjeants-at-Law" (1869). He also wrote several biographies of judges, one being his "Memoirs of the Life of Judge Jeffreys" subtitled "Sometime Lord High Chancellor of England" (1827).
Jeffreys (1645-1689) served as Lord Chief Justice, 1683-1685, and Lord Chancellor, 1685 -1688. He was captured when he tried to flee England after the fall of King James II and imprisoned in the Tower where he died of disease on April 18, 1689, at age forty-three. He is infamous for his conduct on the bench at what has become known as "the Bloody Assizes" in 1685.
Jeffreys is an irresistible topic of articles, gossip and biographies including Henry Brodribb Irving, "The Life of Judge Jeffreys" (1898) and H. Montgomery Hyde, "Judge Jeffreys" (1948).
