International Typographical Union
The International Typographical Union (ITU) was a North American trade union for the printing trade for newspapers and other media. It was founded on May 3, 1852, in the United States as the National Typographical Union, and changed its name to the International Typographical Union at its Albany, New York, convention in 1869 after it began organizing members in Canada. The ITU was one of the first unions to admit female members, admitting women members such as Augusta Lewis, Mary Moore and Eva Howard in 1869.
