Historical characters I have learned about from watching Murdoch Mysteries:

Florence Nightingale Graham (1881-1966), who went by the business name Elizabeth Arden, was a Canadian-American businesswoman who founded what is now Elizabeth Arden, Inc. and built a cosmetics empire in the United States. By 1929, she owned 150 salons in Europe and the United States. Her 1,000 products were being sold in 22 countries. She was the sole owner, and at the peak of her career she was one of the wealthiest women in the world.

Dan Seavey, also known as “Roaring” Dan Seavey (1865-1949), was a sailor, fisherman, farmer, saloon keeper, prospector, U.S. marshal, thief, poacher, smuggler, hijacker, human trafficker, and timber pirate in Wisconsin and Michigan and on the Great Lakes in the late-19th to early-20th century.

John Joseph Kelso (1864-1935) was a newspaper reporter and social crusader who immigrated to Canada from Ireland with his family in 1874 when he was ten years old. They suffered hardships of hunger and cold in their early years in Toronto and, throughout his life, this motivated Kelso’s compassion towards the poor and unfortunate. While a reporter for the World and the Globe, Kelso founded the Toronto Humane Society in 1887 for the prevention of cruelty to children and animals, the Fresh Air Fund and the Santa Claus Fund in 1888 to provide excursions and cheer for poor women and children, and the Children’s Aid Society (Canada) in 1891.

John Ross Robertson (1841-1918) was a Canadian newspaper publisher, politician, and philanthropist. He was elected to the Canadian House of Commons for the electoral district of Toronto East in the 1896 federal election defeating the incumbent. The world of sports was also a focus for Robertson’s public-spiritedness. A fervent advocate of amateur sport, he served as president of the Ontario Hockey Association from 1899 to 1905, which was a critical time period in the history of the sport. His battle to protect hockey from the influence of professionalism caused him to be called the “father of Amateur Hockey in Ontario.”

Cassie L. Chadwick (1857-1907) was the most well-known pseudonym used by Canadian con artist Elizabeth Bigley, who defrauded several American banks out of millions of dollars during the late 1800s and early 1900s by claiming to be an illegitimate daughter and heiress of the Scottish-American industrialist Andrew Carnegie. Newspaper accounts of the time described her as one of the greatest con artists in American history. She pulled off the heist in the Gilded Age of American history, during which time women were not allowed to vote or get loans from the banks, leading some historians to refer to her bank heist as one of the greatest in American history.

Margaret Haile was a Canadian socialist in the late nineteenth and early twentieth centuries, a teacher and journalist by profession. She was active in the socialist movements in both Canada and the United States. Frederic Heath’s “Socialism in America,” published in January 1900 in the Social Democracy Red Book, lists her, along with Corinne Stubbs Brown and Eugene V. Debs, among “One Hundred Well-known Social Democrats”.

Clara Brett Martin (1874-1923), born to Abram and Elizabeth Martin, a well-to-do Anglican-Irish family, opened the way for women to become lawyers in Canada by being the first in the British Empire in 1897. In 1888, Martin was accepted to Trinity College in Toronto. And in 1890, Martin graduated with a Bachelor of Arts in Mathematics at the age of sixteen, which was almost unheard of because of the masculinity associated with that field. In 1891, Martin submitted a petition to the Law Society of Upper Canada to permit her to become a student member, a prerequisite to articling as a clerk, attending lectures and sitting the exams required to receive a certificate of fitness to practice as a solicitor. Her petition was rejected by the Law Society after contentious debate, with the Special Committee reviewing the petition interpreting the statute which incorporated the Law Society as permitting only men to be admitted to the practice of law. W.D. Balfour sponsored a bill that provided that the word “person” in the Law Society’s statute should be interpreted to include females as well as males. Martin’s cause was also supported by prominent women of the day including Emily Stowe and Lady Aberdeen. With the support of the Premier, Oliver Mowat, legislation was passed on April 13, 1892, and permitted the admission of women as solicitors.
