I'll always remember fondly our days in Brooklyn Heights. We all spent many happy years on Pineapple Street, I even look forward to the occasions I get to go back and visit. It brings back memories of city life and of a time when our memories filter out the noise of the day and allow us to dwell on all that is good.

Rest in peace.

Claude and I went to Europe together in the Summer of 1972. We arrived in London tired from our journey and sought a hotel to get some sleep. We gave our passports to the reservation desk and they gave us a room. Up we went and surprise, surprise, their was only one bed. I guess since the last name was the same they thought we were married. We looked at each other and said: "You sleep on that side, I'll sleep on this side. Needless to say, from that point on we made sure to request two beds.

Going to miss you bunches. :(

Claude was my cousin-law. I was jealous that he was Dennis' cousin and not mine.

Claude had a knack for making people feel comfortable. He was the voice of reason. When things were heating up or becoming unreasonable he would say "now wait a second" in a modulated voice. It worked.

One Fall morning in 1972 Dennis and I were going on an outing with a picnic basket full of fried chicken. Claude was in basic training at Fort Dix. We decided to make our outing a visit to see Claude. When we arrived Claude was happy to see us especially since he wasn't too happy with basic training. So the three of us sat on the army base talking and eating fried chicken.

I loved Claude. I will think of him from time to time with good memories and pain in my heart that he is not with us. He was a good, patient, intelligent man and the truth is, I wish he had been my brother not my cousin.

Claude was my cousin and best friend growing up on 63rd street in Brooklyn!
Fond memories of our games of stoopball, stickball and chess.
And our Sunday morning bridge game with Ronnie, Pete and my Mom's meatballs were always special.
