0T the City of Los Angeles, on May 24, 1911, departed this 

 Life, John Daggett Hooker. 

 His achievements in Southern California covered a 

 wide field of activities, and the great number of those who knew 

 him in t lie scientific, commercial and social world will see him no 

 more. Only the memory of his struggles, his successes, his 

 benefaction's and his gentle individuality remains. To those of 

 this Academy of Sciences, with whom he was more intimately 

 associated, his death has eome as a personal affliction. Identified 

 with us. almost Prom its institution, he was a powerful factor 

 in the work which has resulted in our present success, and so 

 he continued until the end. His closing years were devoted to 

 an enthusiastic study of the problems in Astronomy, and the 

 great one-hundred-inch Reflector, now in process of manufac- 

 ture for Mount Wilson, will be an enduring monument to him 

 who conceived the idea of such a telescope, and who made 

 it possible by his munificent endowment. 



In the Bulletin for January, 1909, something was related 

 concerning the character of Mr. Hooker and the progress made 

 in the construction of this instrument, which he so eagerly de- 

 sired to sec completed and in whose work he was so lavish of 

 his time and pecuniary support. What he vainly hoped to see 

 in the realms of outer space, will be revealed to the genera- 

 tions which will follow, and as we sadly erase his name from 

 the active list of members of this Academy we may take a 

 mournful satisfaction in the knowledge thai he was one of us, 

 and that our Academy will be associated with his name, so 

 lone- as his greal benefaction shall endure. 



' At our regular meeting of June 10. 1911, Mr. William II. 

 Knighl introduced a Memorial, which was unanimously adopl 

 ed. H may be read upon another page of this Bulletin.
