He was President of the Standard Typewriter Company which was renamed Corona Typewriter Company in 1914, and merged after his death to form Smith Corona. He was also President of the Groton Mechanics' Bank.
He was a member of the New York State Senate in 1909 and 1910. In January 1910, he opposed the election of Jotham P. Allds as President pro tempore of the State Senate, and accused Allds of having demanded, and received, a bribe in 1901 when both Conger and Allds had been members of the State Assembly. Eventually Allds was found guilty, and resigned first the presidency pro tempore and then his senate seat. Conger himself also resigned his seat, on April 4, 1910, and retired from politics.[2]
He died on February 28, 1922, at his home in Groton, New York,[3] which is now "The Benn Conger Inn".[4]
