Mary Crudelius (n e McLean, 1839 - 1877) was a British campaigner for women's education who lived in Leith, Edinburgh in the 1860s and 1870s, and was a supporter of women's suffrage. She was born in Bury, Lancashire on 23 February 1839 to Scottish parents, and went to a small Edinburgh boarding school in the 1850s. While staying with friends she met her husband Rudolph Crudelius, a German wool merchant, in Leith, and married him in 1861. He travelled a great deal on business and his wife wrote him frequent long letters, including discussion of ideas as well as personal matters. Later she would use her fluency as a correspondent to pursue her social and political causes. In 1866 Mary Crudelius put her name to one of the earliest petitions to Parliament about votes for women. She went on to commit herself to the cause of education for women, starting in 1867 when she spoke out at a ladies' discussion group called the Edinburgh Essay Society. Not long afterwards some of these women, including Crudelius and Sarah Mair, set up the Edinburgh Ladies' Educational Association (ELEA) with the aim of ensuring equal educational opportunities for women.
