Essex County Executive Joseph DiVincenzo was on hand Friday to dedicate the plaque to John P. Doeffinger, a lifelong resident of Belleville. In addition to his work as a docent he also served as president of the Zoological Society of New Jersey.
He died Jan. 13 at the age of 60.

The plaque is located on the patio behind the zoo’s Education Building.
