List of Famous people who died at 66

Heinrich Alexander Stoll was the pen name used by the German writer Heinrich Joachim Friedrich Karl Hans Stoll. During the 1950s and 1960s he emerged in East Germany as a prolific author of adventure novels, historical novels and reworkings of ancient legends, along with short stories and science fiction works. There are nevertheless suggestions that the reality of his own experiences as a young man, during twelve years under Hitler followed by six years under Soviet military administration and the early years of the Ulbricht dictatorship, were a match for almost any novel.

Sir James Frazer Stirling was a British architect.

Peer Raben was a German composer who worked with German filmmaker Rainer Werner Fassbinder.

Jost Metzler was a Korvettenkapitän with the Kriegsmarine during World War II, commander of the U-boats U-69 and U-847, and recipient of the Knight's Cross of the Iron Cross.

Thierry Aubin was a French mathematician who worked at the Centre de Mathématiques de Jussieu, and was a leading expert on Riemannian geometry and non-linear partial differential equations. His fundamental contributions to the theory of the Yamabe equation led, in conjunction with results of Trudinger and Schoen, to a proof of the Yamabe Conjecture: every compact Riemannian manifold can be conformally rescaled to produce a manifold of constant scalar curvature. Along with Yau, he also showed that Kähler manifolds with negative first Chern classes always admit Kähler–Einstein metrics, a result closely related to the Calabi conjecture. The latter result provides the largest class of known examples of compact Einstein manifolds. Aubin was the first mathematician to propose the Cartan–Hadamard conjecture.

Jefferson Howard Sutton was an American author who wrote 23 books of science fiction, war, political and juvenile fiction.
