My condolences to you and your family. When I was informed of Frank's passing, I was in disbelief since Frank was always physically active and mentally alert. As you may recall, Frank & I used to jog regularly at the University and I can attest to the speed & endurance of his long, lanky legs.
At the University, Frank was the epitome of a well learned & independent thinking Professor.On matters that he had an informed opinion, he would carefully listen to various inputs yet always trust his 'inner' judgment. He took a stand on many issues regardless of their popularity. When Frank retired in 2012, the University lost one of its most independent-thinking Professors.
Frank will be missed both as a trusted friend and a respected colleague.
