Edward Jerome "Jerry" Hackman, age 81, of Newark, Delaware, died peacefully on Saturday, August 11, 2012, at his home in Newark. Jerry was born in Jefferson City, Mo., on September 7, 1930, to Oscar Adolf and Rose Helen Pirner Hackman. Jerry attended St. Peter's primary school and graduated from the University of Missouri, receiving a B.S. and M.S. in Mechanical Engineering. Jerry entered the Air Force in January of 1951, and was honorably discharged with the rank of Staff Sergeant, Education Specialist, in January of 1954. During his service he achieved the Air Force Good Conduct and National Defense Service medals. Jerry embarked on his career with E. I. DuPont de Nemours and Company in the fall of 1958. He enjoyed the challenges of mechanical engineering and especially welcomed the opportunity to develop and mentor the associates that worked with him. His career allowed him an opportunity to travel, in which he took great pleasure in meeting his foreign counterparts and learning local customs. Jerry married his late wife, Marcia Ann Hanson, in Albany, N.Y. on October 11, 1952. Jerry and Marcia had eight children and 16 grandchildren during their marriage of over 30 years. Jerry and Marcia raised their family in Albany, N.Y., Jefferson City, Mo., Newark, Del., Richmond, Va., Hockessin, Del., Wilmington, N.C. and finally settled in Newark, Del. Jerry enjoyed playing sports and though sports offered valuable lessons for life. He encouraged his children and grandchildren to participate in a variety of sport activities. As a testament to his beliefs in the importance of sportsmanship, Jerry coached his sons' teams, helped to start the Piedmont Little League and took part in the construction of the baseball field that became part of Sanford High School. Jerry was an avid outdoorsman and enjoyed hunting and fishing. As a means to hone his hunting skills, Jerry started trap and skeet shooting and this particular hobby grew with an ever increasing eagerness for the sport. He worked with many close friends to grow and strengthen the sport in Delaware. Jerry was a member and held various executive roles with the duPont Fish and Game Association and held the position of the National Director for the Delaware Chapter of the National Skeet Shooting Association. Skeet shooting continues to have a loyal following in Delaware due, in part, to Jerry's time and commitment. Marcia predeceased Jerry on November 29, 1983. Providentially, Jerry thereafter met and married Margaret K. "Peggy" Weber in Hockessin, Del. on April 12, 1985. By marrying Peggy, Jerry added a son and, eventually, three more grandchildren. Family and friends played an important part throughout Jerry's life and he cherished many humorous and lasting memories. After over 21 years of marriage, Peggy predeceased Jerry on September 20, 2006. Jerry is survived by his children, John and Donna Hackman, Keith and Joann Hackman, Paul Hackman, Joe and Jackie Hackman, Rosann and Bob Underwood, Beth Pritchard, Mary and Curt Dempsey, Amy and Scott Fix, Barb Hackman, Linda Hryckewycz and Jay and Tina Weber; and 19 grandchildren, each of whom filled him with joy and pride. Jerry is also survived by his sisters-in-law, Nancy Stuart and Lea Hanson. Jerry's family would like to give special thanks to Emmanuel Okornor and Regina Torres from Griswold Home Care and the entire staff at Heartland Hospice for their care and comfort during Jerry's illness. The family will receive friends for a Celebration of Jerry's Life on Sunday, September 30, from 2 - 5 p.m. at the Doherty Funeral Home, 3200 Limestone Road, Pike Creek, Wilmington, DE 19808.

Family and friends have cherished memories of Jerry that they will treasure forever.
