Seymour Benzer 1921–2007

It is now common knowledge that both “Nature” and “Nurture” determine animal behavior. But even as late as the 1970s, the concept that genes have anything to do with behavior was not universally accepted. In the face of such skepticism, Seymour Benzer, working tirelessly at Caltech, refused to join the philosophical debate and, in the way so familiar to those who knew him, shrugged his shoulder...

Seymour Benzer (1921–2007)

Biology lost one of its greats with the death on November 30th last year of Seymour Benzer. In the century that began with the rediscovery of Mendelian units of heredity and ended with the sequencing of the human genome, Benzer’s studies of gene fine structure defined the pivotal moment in the transition from classical to molecular genetics. This quiet devoté of science, with an impish sense of...

Napoleon Polygons

An n-gon is called Napoleon if the centers of the regular ngons erected outwardly on its sides are vertices of a regular n-gon. In this note we obtain a new geometric characterization of Napoleon ngons and give a new proof of the well-known theorem of Barlotti Greber ([1], [3]) that an n-gon is Napoleon if and only if it is affine regular. Moreover, we generalize this theorem by obtaining an an...
