Reflections from distant cuvettes

The main events described in this essay occurred between 30 and 40 years ago. Care has been exercised to describe these events as accurately as possible. I have confined myself to the facts as best I can recollect them now. I have also attempted to recapture the spirit and ambiance of the individual laboratories, their directors, and the scientists working there, leaving philosophical interpretations to others. I feel privileged to have been permitted to work in these laboratories and with these scientists. Despite present difficulties besetting those who desire to devote their lives to scientific research, I encourage these hardy souls to pursue their vision and wish for them the good fortune I had in being associated with so many supportive, brilliant, and interesting researchers.
