  1. We (my wife Ikuko and I) got to know Jim only a few short years ago when he was in the twilight of his wonderfully rich and rewarding life. In that short period where he was neighbor and friend all the qualities and all the many dimensions of the person and man came to light. His strong will, determination, intelligence, wit, integrity and character beyond reproach were his trademarks and he wore them with a simplicity and humbleness that belied his accomplishments throughout his life. I spoke to Jim the day before his passing on and found all those wonderful complexities of his person to be still intact even though he could barely speak or raise his hand. Our condolences to his family. Jim will hold a special place in our heart. May he rest in peace.

  2. I learned the death of your husband from Carol this afternoon when I saw her.He was 89 years of age? My mother died at age 89 in Tokyo in 1991. I have not seen your husband for many months. I was wondering how was he. I saw him several times with a wheel chair before here on the forth floor. I sometime pushed his wheel chair and helped carry a gabage bag to throw on the ground level. He seemed to be a very good and nice man. You told me he was an engineer, but I did not know he had such a great background in study and his careers. I want to send my sincere and deep condelonce to you and your family for the death of your husband. I am sad because I cannot see your husband any more here at this condo. Tatsuo Ozeki
