Ruhl died Thursday.
"Bill was a tremendous businessman, but more importantly, he was a well-respected and admired friend and colleague to many in the Central Pennsylvania community," the tech council said in an email. "His leadership, comradeship and friendship will surely be missed by everyone here at TechQuest and our prayers and well wishes go out to his family."
Ruhl was also a key supporter of TechQuest and was instrumental in forming its infrastructure committee and its board of advisers.
Ruhl retired as chairman, president and CEO of D&E in 2006. During his 15-year tenure, he grew D&E's revenue from $30 million to $175 million. Arkansas-based Windstream Corp. acquired the communications company in 2009 for $333 million.
Ruhl was on the board of trustees for Harrisburg University, which posted a statement about his death, and had represented the United States Telecom Association (USTA) on the President's National Security Telecommunications Advisory Committee.
He received the USTA Distinguished Service Medallion and the Pennsylvania Telephone Association Distinguished Service Award. In 2006, he was inducted into the Central Penn Business Journal's Business of the Year Hall of Fame.
