Biography

edit

Ervin Bauer was born on October 19, 1890 in a family of teachers. He studied medicine in Budapest, then worked in Hungary, Austria, Germany, Czechoslovakia, again in Germany, and finally in the USSR.[3][4] In 1920, when working in Göttingen, he formulated his concept of the sustainable non-equilibrium of the living being in an article[5] (English translation[6]) and then in his first monograph.[7] In 1921, Bauer moved to Prague, where, thanks to the patronage of Wilhelm Roux, he worked at the Institute of General Biology at Charles University. In 1923, Bauer moved to Berlin, where he proposed the dependence of tumour growth on the surface tension of embryonic lymph cells and lymph nodes.[3]

In 1925 Ervin Bauer moved to Soviet Union, where he worked in Moscow at the Institute of Professional Diseases named after V. Obukh, then in the Biological Institute named after K.A. Timiryazev, and at the Second Moscow Medical Institute. From 1933 Bauer lived and worked in Leningrad at the All-Union Institute of Experimental Medicine (VIEM), where he was head of the department of general biology .[8] In 1935, Ervin Bauer published a monograph Theoretical Biology,[9][6] in which he described the general thermodynamic features of living systems. His writings became influential for the development of theoretical biology.[10]

Ervin Bauer's first wife was a writer Margit Kaffka (who died from Spanish flu in 1918), and his second wife was a mathematician Stefánia Szilárd. Bauer and his wife Stefánia were arrested by NKVD on 4 August 1937, and both were shot on 11 January 1938.[11] After the execution of Bauer and his wife in 1938, their publications were banned, and it took years before they could be reprinted.[3] Ervin Bauer was the younger brother of Béla Balázs.

Research

edit

Ervin Bauer formulated the principle of sustainable non-equilibrium state which he considered as the basic characteristics of living matter: “The living systems are never in equilibrium; at the expense of their free energy they constantly perform work to avoid the equilibrium required by the laws of physics and chemistry under existing external conditions”.[6]

Bauer's principle is incorporated into non-linear thermodynamics of irreversible processes.[12] Living systems in this framework cannot support their organization only due to the influx of external energy, i.e. the ordering internal factor is involved. The activity of living system is fully determined by the internal pattern of its non-equilibrium state and any work performed by the biological system appears as the work of its structural forces. The process of evolution, according to Bauer, corresponds to the increase in external work, which aims to exploit additional resources to maintain living state of evolving biosystems.[9]
