The story
The company was founded in 1957 by George R. Bunn, who designed his own versions of paper coffee filters, that had a flat bottom and fluted sides and pour-over drip coffee brewers.
The company introduced its first automatic drip-brew coffee maker in 1963. The company introduced its first drip brewer for the home market in 1972.
On June 26, 2020, a Bunn plant in Springfield, Illinois, became the scene of a workplace shooting in which an employee fatally shot three coworkers before fleeing and committing suicide at another location. The motive remains unclear, according to police.
