Dear Mary, I just heard of Mr Cogan’s passing, please know I extend my sincere condolences to you, his loving wife.  I have many happy memories of my tenor at Hale & Dorr and remember Mr Cogan as a sincere, gentle, kind man, always with a smile despite the burdens and great responsibilities of his position.  He always had time to stop to say hello and a few kind words.  Carol AmbroceoCella
