molding the growing mind of his son, which never could have been 

 obtained otherwise. 



With a true appreciation, however, of the values o£ a liberal 

 education, this scientific interest was not allowed to exert a narrow- 

 ing effect.^ It was not until Aisberg entered the College of Physi- 

 cians and Snrgeons of Columbia University, however, that he 

 allowed himself to devote his entire time to scientific work He 

 graduated with the degree of M.D. in 1900, and received at the 

 same time the degree of A.M. for special research in physiology.^ 

 During the summers and vacations of the Medical School, Aisberg 

 devoted his time to research in physiology with Professor F. S. Lee, 

 and in biological chemistry with Dr. P. A. Levene, now of the 

 Rockefeller Institute of Medical Research, then associate in chem- 

 istry at the Pathological Institute of the New York State Hospitals. 



In July, 1900, after graduating from the Columbia Medical 

 School, Aisberg went to Strassburg, Germany, for post-graduate 

 w^ork, where he studied pharmacology under Schmiedeberg, physio- 

 logical chemistry under Hofmeister, and clinical medicine under 

 Naunyn. Here he also was associated with E. S. Faust, then 

 Privatdozent at the Pharmacological Institute, now professor of 

 pharmacology at Würzburg; also with Wolfgang Heubner, and 

 others. During the succeeding two years his time was devoted 

 almost exclusively to biological chemistry, notably pharmacology, 

 but he continued his interest in clinical and general biological 

 matters, for the study of which there were unusually good oppor- 

 tunities at the University of Strassburg. During this time he con- 

 ducted special investigations into the structure and biological signifi- 



^ C. L. Aisberg was prepared for College by tutors and at the Mt. Morris 

 Latin School, entering Columbia College in 1892. He received the degree of 

 A.B. in 1896. 



^The Department of Physiological Chemistry in the Columbia Medical 

 School was founded in 1898-99, during Alsberg's third year there. At that 

 time only one course in physiological chemistry was offered and that was 

 required of " second year men " in medicine. Alsberg's early interest in physio- 

 logical chemistry was shown by the fact that, while a " third year man " in good 

 Standing at the Medical School, he took, as an elective, the newly established 

 course in that subject for second year men — something no other third year 

 medical Student attempted, then or since. The records show that in spite of this 

 heavy addition to his regulär work, Aisberg stood among the very highest in 

 physiological chemistry and in the entire medical course. [Ed.]
