The use of the title "First Lady" to describe the spouse or hostess of an executive began in the United States. In the early days of the republic, there was not a generally accepted title for the wife of the president. Many early first ladies expressed
First Lady for example "First Lady Tonette Marie Walker of Wisconsin". The practice is less common for spouses of mayors but is nevertheless used for some, particularly in large cities; example: "First Lady Amy Rule of Chicago" or "First Lady Kris Barrett of Milwaukee." Mike Gregoire, husband of former Washington state governor Chris Gregoire, preferred to use his name instead of a common noun, calling himself "First Mike". "First Lady" is also used to refer, less formally, to wives of college and university presidents. It has even been used in reference to female spouses of men who were chairmen of major corporations.
