Martynas Yčas: The "Archivist" of the RNA Tie Club

Between about 1951 and the early 1960s, the basic structure of molecular biology was revealed. Central to our understanding was the unraveling of the various roles of RNA, culminating in the identification of messenger RNA (mRNA) and the deciphering of the genetic code. We know a great deal about the role of Brenner, Crick, Jacob, and Nirenberg in these discoveries, but many others played important supporting parts. One of these is a little-known scientist, Martynas Yčas, who appears in histories, generally without explanation, as the "archivist of the RNA Tie Club." Yčas was born in Lithuania. His father helped write the Lithuanian Constitution in 1919. He studied Roman Law and served in the Lithuanian army before escaping from the Russians in 1940. The records of correspondence of Yčas with the physicist George Gamow and with Francis Crick throw some light on the genesis of our understanding of the role of mRNA. The story of the "RNA Tie Club" illustrates the difficulty in assigning credit for important discoveries and underscores the importance of a free exchange of information, even (or especially) among competitors.
