In 1876 he married FanNy Dickerson, also of Antioch College, in 
collaboration with whom in 1890 he published “A Primer of Darwinism 
and Organic Evolution.” Mrs. BERGEN’s interests turned later to 
American folk lore, to which she has made a significant contribution. 
In 1878, not long after his marriage, Mr. BERGEN returned to 
New England and began his long career as a teacher by becoming prin- 
cipal of the high school at 
Deerfield, Massachusetts. 
Three years later he ac- 
cepted an appointment as 
professor of the physical 
and biological sciences at 
Lombard College, a posi- 
tion which he relinquished 
after 2 years. In 1887 he 
became teacher of phys- 
ics in the Boston Latin 
school. Physics as taught 
in the high schools of the 
time was more often an 
exercise in textbook study 
than one of application of 
principles to laboratory 
practice. Doubtless to 
one of Mr. BERGEN’S 
broad experience and keen 
perception of real values 
the lack of adequate pres- 
entation came home with 
unusual force. In 1891, 
fessor E. M. H ee in collaboration with Pro- 
rE. M. Harr of Harvard University, Mr. BERGEN brought out the 
well known textbook in high school physics which had a far-reaching 
and permanent influence on the teaching of this science in America. 
Although his chief interest was later transferred to botany, he main- 
tained an active connection with the teaching of physics by acting for 10 
years as instructor in this branch in the Harvard summer school.
