Reviewing one’s career in order to write for Recollections is a very moving experience for an author (rather like what is said to happen in the process of drowning), but interesting a reader in such a review requires adding something. What I have tried to weave into my saga is a personal view of how my field has developed.Sometime during the course of my university years, I concluded that “achievement” in science consists of studying a significant phenomenon well enough to show in mathematical formalism that what happens is just what one expects from applying the Great Laws to the system under study. After completing graduate school, experiencing a war, and obtaining employment at a great university, beginning my quest seemed to require only the selection of a significant phenomenon. The phenomenon turned out to be biological contractility-in retrospect a good choice, but, at the time, one reached by pure accident. The year was 1946, that is, 48 years before this assessment. In socio-science, it is erudite to affirm that “everyone stands on the shoulders of someone else,” and in this way work back to Babylonian or Mayan authors, but in my quest only two previous contributions really mattered. Seven years before, VA Engelhardt and this wife, Lubimova, extracted from muscle the protein,“myosin,” and showed that when this protein was drawn into threads and supplied with the enzymatic substrate, ATP, the mechanical properties of the threads changed as the ATP was consumed. A few years later, Albert Szent-Gyorgyi and his associate, Straub, showed that “myosin” was a complex of two proteins-real myosin (the ATPase) and an essential partner protein that they named actin. Perhaps I should admit that now we
