Janis Stradins (10.12.1933Stradins (10.12. -29.11.2019) was a well-known expert in molecular electrochemistry, ESR spectroscopy and physical organic chemistry, as well as in history of sciences. His main works in electrochemistry were connected with organic molecules single electron reduction and oxidation primary and secondary products studies, these species ESR spectra hyperfine structure investigations, supplying data on various organic molecules groups' reactivity, demonstrating abilities of electrochemical studies for organic compounds reaction prediction. He was ISE member, past president of Latvian Academy of Sciences, full member of European Academy of Sciences and Arts, from 2011 its Honorary Senator.
