Joseph Bartlett Teas (July 4, 1800 - February 23, 1872) was an American lawyer and minister from Mt.
At the age of 13, during the War of 1812 he accompanied his father to the front and was allowed to serve as a teamster, earning a land grant and a pension.
On October 27, 1838, the Teas brothers advertised in the Iowa Territorial Gazette that while they had formerly practiced law in Burlington they were now in Mount Pleasant.
The session met in Green Bay on January 1, 1836; Smith and Teas made the journey on horseback, in mid-winter through deep snows.
He died February 23, 1872, leaving his widow and twelve surviving children (at least three daughters had pre-deceased him).
