On April 15, 2002, Yurii Gertsovich Yurovitskii
passed away. He was a well known scientist, specialist
in the ﬁeld of developmental biology, ecological bio-
chemistry, and ichthyology. Yurovitskii made a signiﬁ-
cant contribution to the studies of biochemical and eco-
logical problems of development. He was the author of
more than 150 publications, including three mono-
graphs published in this country and abroad.
Yu.G. Yurovitskii was born in Moscow on Decem-
ber 17, 1930. In 1948, he entered the Biological Fac-
ulty, Moscow State University, where he studied at the
Department of Ichthyology headed by the Correspond-
ing Member of the USSR Academy of Sciences
G.V. Nikol’skii. After graduation from the Moscow
University in 1953, Yurovitskii entered the postgradu-
ate school at the Institute of Inland Waters, USSR
Academy of Sciences, in Borok, Yaroslaval’ District. In
1958, he got his candidate degree (PhD) for the thesis
Biologiya cintsa Rybinskogo vodokhranilishcha
ogy of the Blue Bream in the Rybinsk Water Reser-
voir), which he wrote under the supervision of
Prof. S.G. Kryzhanovskii.
All subsequent scientiﬁc activities of Yurovitskii was
related to the Severtsov Institute of Animal Morphology,
USSR Academy of Sciences (since 1967—Kol’tsov
Institute of Developmental Biology), where he came as
junior research worker in 1956. His work in the Kryzha-
novskii’s laboratory was dedicated to the analysis of eco-
logical problems of ﬁsh development, speciﬁcally, inﬂu-
ence of oxygen conditions on embryogenesis.
In 1961–1969, Yurovitskii headed the Kropotovo
Biological Station of the Institute, where he showed
himself as an efﬁcient leader and contributed a lot to the
scientiﬁc and current activity of this unique station.
In 1963, Yurovitskii joined the newly formed Group
of Space Biology headed by A.A. Neyfakh and
A.I. Zotin, which was reorganized in 1965 in the Group
of Developmental Biophysics (A.I. Zotin) and Group of
Developmental Biochemistry (A.A. Neyfakh). In 1967,
when the Institute of Developmental Biology was
formed from the Institute of Animal Morphology, the
Group of Developmental Biophysics was reorganized
in the Laboratory of Developmental Biophysics, where
Yurovitskii worked until the last days of his life.
For many years, Yurovitskii worked together with
Lev S. Milman. They carried out fundamental studies
of the regulation of carbohydrate metabolism during
early development of ﬁsh, which were widely known
not only in this country, but also abroad. They were the
ﬁrst to study speciﬁc features of carbohydrate metabo-
lism at different stages of early development: during
oocyte growth and maturation, fertilization, and various
embryonic stages. The succession of carbohydrate
metabolism types discovered by Yurovitskii and Mil-
man was one of si9gniﬁcant achievements in biochem-
ical embryology in the 1970s.
In 1973, the results of these studies were summa-
rized in two monographs by Milman and Yurovitskii:
Mekhanizmy enzimaticheskoi regulyatsii uglevodnogo
obmena v rannem embriogeneze
(Mechanism of Enzy-
matic Regulation of Carbohydrate Metabolism during
Early Embryogenesis) (Moscow: Nauka, 1973) and
Regulation of Glycolysis in the Early Development of
(Basel: Karger, 1973). These mono-
graphs presented a comprehensive analysis of the
mechanisms underlying the regulation of carbohydrate
metabolism at different developmental stages, based
predominantly on the authors' results.
In 1974, Yurovitskii got his doctoral degree for the
Regulyatsiya uglevodnogo obmena v oogeneze
(Regulation of Carbohydrate Metabolism in Fish
Oogenesis), which can be considered as a completion
of one of the most signiﬁcant period of his research
activity related to the analysis of biochemical mecha-
nisms of development.
During the last 15 years, the scientiﬁc interests of
Yurovitskii were related to the problems of ecological
biochemistry, speciﬁcally principles of ecologobio-
chemical monitoring. This work was carried out
together with the well known biochemist and ecologist
V.S. Sidorov, founder of the school of ecological bio-
chemistry at the Institute of Biology, Karel Scientiﬁc
Center of the Russian Academy of Sciences. The results
of these studies were widely known and supported by
specialists in the area of nature conservation. They were
summarized in the collective monograph
(Safety of Life Activity) published
Yurovitskii paid a signiﬁcant attention to teaching.
He was reading a course of lectures on problems of
ecology at the Moscow Aviation-Technological Insti-
tute and International University “Dubna”. The process
of teaching always captivated him and he was very ear-
nest about it.
The death of Yurii Gertsovich Yurovitskii is a great
loss for our science, for the Kol’tsov Institute of Devel-
opmental Biology, for the Laboratory of Developmen-
tal Biophysics, and for his colleagues and friends.
