48 PROCEEUINCiS OF TUE 



attracted the notice of De B;iry, wiio offered liim iin assistant's 

 place in tlie Strasburg Institute, and in acceptini^ it, lie entered 

 upon a new career. Iti January 1SU7 lie put forward a new 

 thesis on the East Prussian Desuiids for liis doctorate. 



At this lime De JJary had a crowd of disciples round him, .xucli 

 as Errera, Arthur AJeyer, Stahl, Mattirolo, Pirotta, and with these 

 Klohs came into the friendliest relations. A year of military duty 

 closed the iStrashurg life for him. 



Desirous of learnnig in other fields of research, Klebs turned to 

 AViirzburg on being released from military duties, where Sachs 

 was lecturing; here a year was spent, after which he migrated to 

 Pfetfer's laboratory. 



Klebs was just -o when in October 1882 he betook himself to 

 Tiibingen. Here he set to work on ' Microarganisnien ' and 

 ' 13au niid Physiologic der Pflaiizenzellen.' Special interest was 

 repeatedly displayed by him in the structure of IIifdro<iicti/on, and 

 maniiscrijjt left by him shows tliat even late in life he resumed 

 investigation on it. Another topic he took up was the germina- 

 tion of seeds. 



In 1887, after Pfeffer had been called to Leipzig and Vochting 

 came from Basel to succeed him, Klebs went to Basel, where he 

 was very successful, and there married a young wife, Luise Sigarart. 

 His labours on the mechanism of the development of the lower 

 organisms, and the systematic disposition of Algae bore abundant 

 returns. 



In 1892-1)3 he was Rector of the University of Basel, and his 

 address was on the relation of sex in Nature. 



During the last decade of the nineteenth century, Klebs was 

 enabled to erect a new botanic institute in Basel, but had hardly 

 0|)ened it, wlien lie was called to Ilalle in succession to Krauss, 

 Here also he had to busy himself with new buildings — a new 

 laboratory and class-room and glasshouses were speedily completed. 

 Sempervivum and ISedam were studied for variation, which led on 

 to Ivlebs's first memoir on physiological cheniistiy. 



In 1907, in consequence of the deatli of Pfeffer, he received a 

 call to Heidelberg, which he gladly accepted, and there spent a 

 series of successful years. Whilst here he was able, in 1910-11, 

 to travel through Siberia, Japan, Java, and India, and with several 

 comi)anions to visit Armenia, the Caucasus, and Southern Ilussia 

 in 1912; also, in 1913, a trip to Egypt with his wife. 



Latterly he devoted liis attention to the question of tlie amount 

 of mineral matters taken out of plants, occasioned by rhythmic 

 niovemcTit, light, and other circumstances. His nature was that 

 of an investigator, and travelling gave the chance for so much 

 that was new that he eagerly seized this, but the great war laid 

 a heavv burden on iiim, and he turned to his researches. 



On the loth October, 1918, Klebs died of influenza after a 

 short attack, and on the 18th he wns cremated. He had been 

 chosen to assume the position of Eeetor a few months later; 

 many Universities had bestowed their honours upon him, our own 

 Society electing him a Foreign Member on the 4th May, 1911.
