JAMES EDWARD KEELER. 



The sudden death of Professor James E. 



Keeler, Director of the Lick Observatory, 



which occurred at San Francisco on August 



12th, removes one who stood at the very 



forefront of astrophysical research. The 

 advanced position occupied by the United 

 States in the development of astrophysics 

 is due as much to Keeler as to any other 

 individual. The high quality of his own 

 investigations, and the effect of his example 

 on the work of others, have been factors of 

 the first importance in building up the 

 physical side of astronomy in this country. 

 The shock caused by his wholly unexpected 

 death has been felt by many, not least by 

 some of those whose friendship for him grew 

 out of a common interest in his own field of 

 science. 



As he was still in his forty-third year, and 

 had until recently enjoyed the best of health, 

 there seemed to be every reason to expect 

 that his important contributions to astro- 

 physical literature would continue for many 

 years to come. But a severe cold, con- 

 tracted in the course of his recent work with 

 the Crossley reflector, developed into pneu- 

 monia, which was complicated with heart 

 trouble. From the accounts which have so 

 far reached us it appears that he withstood 

 this first illness, and had just entered a 

 hospital in San Francisco, when he was 

 seized with an apoplectic stroke from which 

 he did not rally. 



James Edward Keeler was born at La 

 Salle, Illinois, on September 8, 1857. As 

 a boy he was greatly interested in science, 

 and I have often heard him speak of his 

 early chemical experiments and astronom-
