Obituary of James Gerard Sheridan

Sheridan, James (Jim), passed away peacefully on September 18, 2023, at the age of 96 surrounded by his family and loved ones in Windham, N.Y. He is survived by his wife of 68 yrs, Joan Sheridan, whom he adored, seven children, and their spouses, fifteen grandchildren, and six great-grandchildren.


Jim was born in New York City on December 10, 1926, one of twelve children born to Senator and Mrs Thomas I. Sheridan.  He attended the Loyola School, and then went on to Columbia University and Fordham University before leaving to enter a Jesuit seminary for five years. Upon leaving the seminary he went to the University of Oklahoma where he received his graduate degree in petroleum engineering.   


On April 16, 1955, Jim married his wife Joan.  Their marriage was celebrated at the Saint Ignatius Catholic Church on Park Ave, after which they returned to Oklahoma in order for Jim to complete his graduate degree. 


Upon graduating, Jim and Joan moved to Louisiana and Jim began a career in the oil business with Texaco.  However, the distance from their large families and all of their friends in NYC eventually drew them back home, where Jim began work at National Securities in the mutual fund business. 


He raised his family and maintained a home in Manhasset, NY for over thirty years. 


Over the years, Jim would change careers in an effort to fulfill his passion to give back.  He taught for many years in the tough schools of East New York where his gift for making people feel valued and loved, and his tremendous sense of humor made him a much beloved teacher.


After retiring to Windham NY, Jim went back to his old love of petroleum engineering and used his expertise working with the New York State Dept.

of Conservation.


His deep faith and total devotion to our Lord guided him throughtout his life.  For many years, he was a daily communicant at St Theresa of the Child Jesus R.C. Church


Jim is survived by his beloved wife, Joan, daughters Deirdre Haltermann (Bill), Joan Oldknow (Kent), Theresa Hueglin (Roger), Maureen Matin (Michael), sons James Sheridan Jr ( Nancy), Paul Sheridan (Karen), Michael Sheridan, his grandchildren, William (Tanmayata), Victoria(Rob), and Timothy Haltermann, Bryan, Sean(Kristin) and Kent Oldknow II, Roger and Michael Hueglin, Julia (Daniel) and James (Diandre) Matin, Nicole (Colin) and James Sheridan, John (Lili), Cavan (Jennifer) and Kate Sheridan, and six great grandchildren Jack, Sienna and Chloe Cassidy, AJ and Owen Palandati and baby Sheridan on the way.


Jim is pre-deceased by his parents, Senator Thomas I. and Marie Sheridan, his brothers, Thomas II, Paul, Jerome, Robert, and Kevin and his sisters, Mary, Anne, Claire, Jeanne, Elizabeth, Mabel (Sr Mary Christopher), and countless nieces and nephews, each of whom loved him.
