William Herbert Wallace (29 August 1878 – 26 February 1933) was convicted in 1931 of the murder of his wife Julia in their home in Wolverton Street in Liverpool's Anfield district. His conviction was later overturned by the Court Of Criminal Appeal, the first instance in British legal history where an appeal had been allowed after re-examination of evidence.
The case, with its strange background, has long been the subject of speculation and has generated many books, being regarded internationally as a classic murder mystery.
William Herbert Wallace was born in Millom, Cumberland, in 1878. He had a younger brother and sister. On leaving school at fourteen he began training as a draper's assistant in Barrow-in-Furness. On finishing his apprenticeship he obtained a position in Manchester with Messrs Whiteway Laidlaw and Company, outfitters to Her Majesty's Armed Forces and the Colonial, Indian and Foreign Services. In 1903, after five years' service, Wallace obtained a transfer to the company's branch in Calcutta, India, where he remained for two years. On the suggestion of his brother, Joseph, who lived in Shanghai, in 1905 Wallace sought another transfer to Whiteway Laidlaw's branch in that city.
A recurrent kidney complaint resulted in Wallace resigning his position and returning from China to England in 1907, where his left kidney was removed at Guy's Hospital. Little is recorded of Wallace's life after this time, until he obtained a position working for the Liberal party in Harrogate, rising to the post of election agent in 1911. During his time in Harrogate he met Julia Dennis (28 April 1861 - 20 January 1931), and they were married there in March 1914. All early sources suggested that Julia was approximately the same age as Wallace, but in 2001 James Murphy demonstrated from her original birth certificate that she was actually seventeen years older than he was. Her father was a ruined alcoholic farmer from near Northallerton.
