It is now almost a hundred years since Fournier, much against the standard belief of the times, proposed that syphilis was the likely cause of tabes dorsalis. Alfred Fournier (Fig. 1) was unquestionably the foremost syphilologist in France in the last 30 years of the 19th century, but his life and works are little known in English-speaking countries, probably because so few of his works have be...

Alfred Klemm on his 100th Birthday

After completing my studies in physics at the university in Frankfurt (Diplom), I started my PhD work in the group of Professor Alfred Klemm at the MaxPlanck-Institut für Chemie in Mainz on November 1, 1958. In my thesis, I measured the difference in thermal conductivity between oand p-H2 at 20 K. Alfred Klemm’s main area of research was molten salts; this subject, however, resulted from his co...

Dachsous (Dchs), an atypical cadherin, is an evolutionarily conserved regulator of planar cell polarity, tissue size and cell adhesion. In humans, DCHS1 mutations cause pleiotropic Van Maldergem syndrome. Here, we report that mutations in zebrafish dchs1b and dchs2 disrupt several aspects of embryogenesis, including gastrulation. Unexpectedly, maternal zygotic (MZ) dchs1b mutants show defects i...
