Doug Emhoff became the first second gentleman of the United States when his wife Kamala Harris became vice president in 2021.
The first man to formally serve as first gentleman was James E. Ferguson in 1925, a former governor of Texas who was forced from office due to corruption charges, and whose wife Miriam A. Ferguson later won the office.
The first man to serve as first gentleman without having previously served as governor was Thomas Grasso in 1975, husband of Connecticut governor Ella T. Grasso.
In 2019, Colorado governor Jared Polis' husband Marlon Reis (who at the time was his partner), became the first same-sex partner to receive the title of First Gentleman (in addition to being the first same-sex partner of a sitting governor).
Six states have had more than one first gentleman: New Hampshire with four, Arizona and Kansas with three, and Connecticut, Michigan, and Oregon, all numbering two.
