Olga Alekseevna Khazova (1933-2023) was a graduate of Moscow Chemical-Technological Institute (МХТИ). She completed her PhD on methanol adsorption and oxidation on platinum in 1965, and became the closest collaborator of V.S. Bagotsky and Yu.B. Vassiliev in further fuel cell oriented research.

Villi Shelevich Palanker graduated from Moscow Chemical-Technological Institute (МХТИ) and moved to Frumkin Institute from the Institute of Power Sources as a member of Bagotsky’s team. His 1967 PhD thesis was devoted to ‘double layer’ on mercury in concentrated solutions and low-temperature melts. The next topic was Pt-support interaction in respect to electrocatalysis of hydrogen reactions. In early 1970s he decided to leave for Israel, but could not obtain the permission from soviet authorities for many years. In a hope to enhance this procedure (more fast in national republics of the USSR) he left for Alma-Ata, Kazakhstan, where he was employed in the Institute of Organic Catalysis and Electrochemistry headed by D.V. Sokolsky. There are five excellent Palanker’s articles of Alma-Ata period, on tungsten carbide electrocatalyst, published in 1975-1977 in international journals. Later he left for Yerevan, Armenia, and was finally allowed to immigrate already in 1980s.
