Henry Corry Rowley Becher was born June 5, 1817 in London, England, the youngest son of Captain Alexander Becher, Royal Navy, and Frances Scott Becher. He immigrated to London, Ontario in 1835.
Becher began his legal career by articling with John Wilson and was admitted a law student at Osgoode Hall in 1836. He was appointed Registrar of the Surrogate Court of Middlesex County in 1839. Admitted as an attorney in 1840 and called to the bar in 1841, Becher was elected a Bencher of the Law Society of Upper Canada in 1853 and called to the bar at the Inner Temple, London, England in 1882. Becher was partner with Samuel Barker and William Purvis Rochfort Street in the law firm of Becher, Barker and Street. The firm became Becher, Street & Becher, when his son, Henry Becher, was admitted to a partnership in 1872. He served as solicitor for Colonel Thomas Talbot in the 1850s, drawing up the will that bequeathed the bulk of Talbot's estate to George Macbeth and settling a dispute between Talbot and his nephew Richard Airey; was involved in the settlement of the estate of George Jarvis Goodhue in the 1870s; and served as municipal solicitor for London from 1849 to 1853. In April and May of 1855, he alone handled the crown business at the assizes at St. Thomas, London, and Chatham, and submitted civil briefs at St. Tomas and London. Becher completed the transaction in which the Huron Diocese acquired Rough Park, the estate of Lionel Ridout which became the first site of Huron College in 1863. In 1856, Becher was appointed Queen's Counsel and lectured for a tern at Osgoode Hall. He became solicitor for the Gore Bank and a director of the Great Western Railway in 1857.
Becher served on the London town council from 1850 to 1854. Attempting to enter provincial politics, he failed obtain the Conservative nomination for London in 1857. He won the nomination in 1860, but lost the by-election. In 1861, he again vied for the nomination, but withdrew, after the intervention of John A. MacDonald, to stand for the Legislative Council for Malahide. Defeated, Becher did not run again for public office; however, he remained an active party organizer.
Becher built Thornwood on 13 acres in London, and took up residence there in 1845. He rebuilt the house after it was destroyed by fire in 1852. Becher travelled extensively in Europe, visited the Middle Ease, made several trips to Florida, and wrote A Trip to Mexico after travelling there 1878. In 1880, Becher became a fellow of the Royal Geographic Society. His diary has been published in the London Advertiser in 1926 and in Papers and Records of the Ontario Historical Society in 1939.
Becher married Sarah Evanson Leonard, daughter of Richard Leonard, the sheriff of the Niagara District, on October 27, 1841. Together, they had seven children: Frances Anna Maria (born 1842), Alexander (1844), Henry (1846), Richard Leonard (1848), twins Florence Mary and Constantia Ann (1850) and Alice Ethel Jane (1857), who died in infancy. Sara Becher died in 1864. On August 20, 1874, Becher married Mrs. Caroline Robertson, daughter of Samuel Street of Niagara Falls.
