In Memoriam – Alexander I. Leontiev

It is with great sadness that we announce the passing of Professor Alexander Ivanovich Leontiev on 30th November
2022. Alexander Leontiev graduated fromMoscow Aviation Institute in 1950, and in1963 became a Doctor of Science in Engineering. A few years later, in 1965, hebecame a full Professor. He was elected
an Academician of the Russian Academy ofScience in 1991. Professor Leontiev was aleading ﬁgure in thermal physics research, particularly in convective heat transfer and related topics.
One of the most fruitful periods of scientiﬁc activity of Alexander Leontiev was his work in the Institute of Thermophysics of theSiberian Branch of the Academy of Sciences of the USSR from 1959
to 1968. He founded there the Laboratory of Thermal Gas Dynamics, whose extensive subject matter included studies of heat transfer processes in turbulent convection, phase transitions, and combustion in power engineering. The research community, the foundation of which was initiated by Alexander Leontiev during theseyears, successfully developed with his participation during the following decades and continues to work nowadays.
After returning to Moscow, Alexander Leontiev lectured on heattransfer and headed a department at Bauman University. He wasalso the founder and head of a laboratory at the Institute of Mechanics at Moscow State University. For the past few years, he has
led one of the research topics at the Joint Institute for High Temperatures.
Academician Leontiev’s creative work has embraced the mostsigniﬁcant period of the development of thermal sciences in theformer Soviet Union and in the Russian Federation. It includeswell-known achievements in such areas as boiling, boundary layer
theory, and combined natural and forced convective heat transfer. His work at the leading science centres in Novosibirsk andMoscow has resulted in Academician Leontiev becoming the leaderof the entire community of Russian researchers working in the areaof heat transfer. He was Chairman of the National Committee ofhttps://doi.org/10.1016/j.ijheatmasstransfer.2022.123768

Heat and Mass Transfer of the Russian Academy of Science anda member of the editorial boards of several Russian and international journals including the International Journal of Heat and Mass
Transfer and the International Communications in Heat and MassTransfer.
Professor Leontiev has been the permanent chairman of theRussian National Committee for Heat and Mass Transfer since 1995.
Over several decades, Alexander Leontiev has been leading theRussian delegations to numerous international science forums andhas participated in the activities of the International Centre forHeat and Mass Transfer (ICHMT) as an elected member of the Executive Committee and Vice President of ICHMT. His incisive intelligence and natural personal charm, friendliness and extremelywonderful sense of humour, made a personal relationship withSasha (as he was called by friends and colleagues from many countries) not only rich and interesting but also extremely pleasant.
Alexander Leontiev has received numerous scientiﬁc awards inthe ﬁeld of heat transfer research, including the Luikov Medal,
which is the highest international award in the heat transfer community. Since 2008, Professor Leontiev is an elected foreign member of the US National Academy of Engineering. In 2010, he wasawarded the Global Energy Prize for fundamental research in theﬁeld of intensiﬁcation of heat transfer in power plants.
Alexander Leontiev has educated at least two or even three
generations of specialists in the science of heat transfer. Under
his leadership, seminars were regularly conducted for young scientists, referred to as the “Leontiev Schools”. Many leading researchers working in scholarly laboratories all over the world were
proud to call themselves Leontiev’s students. The relationship with
Alexander Leontiev gave the young researchers not only professional knowledge but helped them to become cultural personalities, appreciate their colleagues, and to form positive human qualities.
Alexander Leontiev’s interest in all aspects of life and his natural optimism have inspired his friends and colleagues. His wisdom,humour, kindness, and leadership in the heat transfer community
will be missed by many friends and colleagues worldwide.
