My husband James L. Buie died Sept. 23 from emphysema caused by smoking. I want to thank The Times for its obituary (Part I, Sept. 28) which outlined some of Jim's contributions in the field of microelectronics.
Although Jim quit smoking 10 or 11 years ago, he quit too late. There was little improvement in his lungs, which continued to deteriorate much more rapidly than the natural deterioration due to aging.
When people have talked to me offering their condolences and asked if there was anything they could do, I have replied to a smoker, "Yes, stop smoking," or to a nonsmoker, "Vote yes on Proposition 99 to increase the tax on cigarettes."
Jim officially retired in 1978 from TRW as a full-time worker, but later began working under contract as a part-time consultant for TRW/LSI Products. During those years he was awarded additional patents and designed additional integrated circuits (chips) that are still being placed in electronic devices. During the last three years he has been on an oxygen supplement, but with the aid of a small portable oxygen tank he was still able to continue his consulting. But finally, in March of this year, it became physically impossible for him to make the trip to the offices of TRW/LSI Products, although he did continue to do some work on his home computer and communicate with TRW by telephone or mail. But a few months ago he found that he was no longer able to do even that.
