I am so sorry to hear of Herbie's passing. He was a wonderful, kind man. I've known and been a friend of Herbie for 27 years at Princeton. I hurt so for the family. He came to see me his last day before retirement. We had a good talk and I got a hug from him. He didn't get to enjoy his retirement. God Bless each and everyone of you in the Whitson family. We've lost a great friend !
