strange laboratory, so that he might manage 

 things there just as in his own rooms. Every- 

 thing must be carefully tested before he began 

 his lecture. So it came about that his demon- 

 strations became the star jwrformances and 

 attractions of each of these meetings. 



It is difficult to enumerate all the pieces of 

 apparatus for purposes of instruction and in- 

 vestigation which we owe to him. These are 

 almost all published in our magazine, in 

 which he took a lasting interest. Even the 

 first volume in 1888 contained a report of his 

 paper in which he published a new method of 

 measuring the intensity of a tone. In the sec- 

 ond volume there appeared the first original 

 investigation from his hand, in which he de- 

 scribed two pieces of apparatus for detecting 

 the nodal points and internodes in a sounding 

 column of air. His last lecture, which he 

 gave in the spring of 1914 upon a new and 

 simple means of showing the interference of 

 light, he had also intended for our magazine. 

 However, before he came to write it down, the 

 war had pressed into his hand the sword in- 

 stead of the pen. 



Of his books only two may be mentioned 

 here : the large " Lehrbuch der Physik " ^ 

 which has in five years gone through three edi- 

 tions and the "Didaktik und Methodik der 

 Physik " ^ (a part of Baumeister's Handbook) 

 which in spite of its brevity and its strong 

 personal color, is rich in valuable advice and 

 fruitful ideas. 



Death has brought his work to an untimely 

 end, but the influence of this creative work 

 will live after him and will assure for him a 

 grateful memory among his followers as well 

 as in the history of the teaching of physics.
