Walter Bock
German chemist

Walter Bock (20 January 1895 – 25 October 1948) was a German chemist who developed styrene-butadiene copolymer by emulsion polymerization as a synthetic rubber (SBR).
Early life
Walter Bock was born on January 10, 1895, in the small village of Wenzen (now part of Einbeck) in the Duchy of Brunswick. He was the fourth of nine children. His father, Wilhelm Bock, was the sole teacher in Wenzen. From 1905 to 1914 Bock attended high school in Brunswick.
Immediately after graduation he joined the army and served as an officer in World War I. He commanded an infantry company until he was wounded in July 1918.
In October 1918 he began studying chemistry. After receiving his Ph.D. from the University of Göttingen in October 1921, Bock found employment as chemist at the Köln Rottweil AG in Premnitz. In the fall of 1924 Bock joined the Dr. Zellner laboratories in Berlin, where he took charge of the chemical-pharmaceutical department.
This brief starts where responsible research should: with the source description of “Walter Bock” as german chemist. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as german chemist. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 1, 2026. The linked authority identifier is Q15990398. VIAF identifies the subject as 303011432. 2 of 2 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank. The first chronological checks are 1895, 1948, 1905 and 1914.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
