John J. Cone

John J. Cone was the fourth Supreme Knight of the Knights of Columbus from 1898 to 1899 and Fire Commissioner of Jersey City, New Jersey.

Cone was a founding member of Jersey City Council #137 of the Knights of Columbus on November 3, 1895. In less than three years was elected Supreme Knight after Supreme Knight Hayes died suddenly from complications from peritonitis.

During Cone's time in charge, the Knights subscribed to war bonds in order to support the Spanish–American War. He also directed that soldiers and sailors were not to be disqualified from being insurance members. By the end of his time as Supreme Knight the order had reached as far west as the state of Minnesota.

Cone died at his home in January 1937. He was 79 years old.
