Alexandre Guilliermond was born in 1876. 

 He obtained his Ph.D. degree at the Sorbonne 

 in 1902 and worked for many years at the 

 University of Lyo7is. He came to Paris about 

 1921; at that time he was already famous for 

 his work on the development, sexuality, tax- 

 onomy and phylogeny of the Endomycetes and 

 Saccharomycetes ; the higher Ascomycetes; the 

 cytology of the Cyanophyceae and Bacteria; 

 starch formation; and especially on account of 

 his research and theories on the chondriome 

 and vacuome. He was appointed Chairman 

 of the Department of Botany at the Sorbonne 

 in 1935, and elected a Membre de I'lnstitut in 

 the same year. Most of his later papers and 

 those of his students (among whom Eichhorn, 

 Plantefol, Mangenot and Gautheret should 

 be mentioned) have been published in his own 

 journal, the Revue de Cytologie et de Cyto- 

 physiologie Vegetales. He married Helene 

 Popovici, at one time his assistant, the 

 daughter of Professor Popovici of lasi in Rou- 

 mania. His principal publications are being 

 listed on pages 229/232 of this volume; cf. also 

 "Titres et Travaux Scientifiques de M. A. 

 Guilliermond" (Lyon / Rey, 1921) and Chron. 

 Bot. 11:128* (1936).
