Alexander Chudakov was the first to do many things in science. Presented below is a short review of his work including pioneering experiments that the fates surely favored, in the sense that Chudakov's ideas and the methods he suggested were realized in many subsequent experiments and even in whole branches of science. Some large modern projects are mentioned, those either in operation or only in the design phase, the path to which started from the pioneering initiatives of Chudakov and their first practical implementation.
