A REVIEW OF THE SCIENTIFIC WORK OF 

 H. L. RUSSELL 



E. G. HASTINGS 



It is impossible to present in a few pages an adequate 

 statement of the work of him in honor of whom this volume 

 is issued. In most of the fields that engaged his attention, 

 as a member of the Wisconsin Experiment Station staff, the 

 Avork was of a pioneer nature and has served as a foundation 

 for the work of others who were to follow, making a more 

 detailed study of the varied fields. 



The University of Wisconsin has been fortunate in the 

 loyalty of its staff and in the cooperation that has existed be- 

 tween its various departments. The work presented by Dr. 

 Russell in many of his papers was done in association with 

 colleagues in other departments of the College of Agriculture. 

 Chief among these collaborators may be mentioned Dr. S. 

 M. Babcock whose knowledge of the chemistry of the dairy 

 supplemented and indeed made possible much of the work in 

 dairy bacteriology, a subject that is as much chemical as 

 biological in nature. 



Men are creatures of circumstances. Their careers are 

 governed largely by their associations. One of the great 

 factors in directing the future of the subject of this sketch 

 was his father, a medical man by education, a scholar by 

 nature, who realized the value of a university education 

 and who made possible the years of graduate study. H. L. 

 Russell was born on March 12, 1866, son of E. Fred Russell 

 and Lucinda Estella Russell. He entered the University of 

 Wisconsin in 1884, receiving his bachelor's degree in 1888. 



Another important factor in the determination of the future 

 career of the student was the presence in the University of 

 Wisconsin of William Trelease, now in charge of the depart- 

 ment of botany in the University of Illinois. Dr. Trelease
