For 30 years, Mr. Hendrick was a member and lector at St. Dorothy Parish in Drexel Hill. Later, he was a 27-year member of St. John Chrysostom Catholic Church in Wallingford.
On Veterans Day 2005, Mr. Hendrick, along with Ed Buffman and Media Mayor Bob McMahon, opened the Pennsylvania Veterans Museum on State Street in Media.
The trio collected military memorabilia and oral histories from veterans of all military branches. The stories were videotaped and presented in interactive kiosks, along with displays providing visual history lessons.
"There was one kiosk for each branch of the service, and one for women," said his daughter, Barbara Murphy. "There were packs with parachutes that they would let the kids try on to see how heavy they were."
His family said the aim of the museum was to teach the public, especially children, about the experiences of veterans and the sacrifices they made during wartime in the name of freedom and security.
Mr. Hendrick served as vice chairman and curator of the museum until he became ill in 2011.
"The museum was his passion," his family said in a tribute. "He told everyone he met to go there and take their families. He gladly served as tour guide when friends visited, even when leg weakness limited his mobility."
In honor of Mr. Hendrick's experiences as a Navy war veteran, his granddaughter Sharon Ferry wrote a children's book in 2010 explaining Veterans Day to young children. It was titled Granddad Bud. Mr. Hendrick and his granddaughter did book signings, which were well attended, Murphy said.
Mr. Hendrick's wife, Alice Gallagher Hendrick, died in October 2013. They had been married for 71 years.
Surviving, besides his daughter, are two other daughters, Donna Procaccio and Meg DeFeo; son Jack; 16 grandchildren; and 25 great-grandchildren.
Services were Saturday, June 28.
