GROVE KARL GILBERT: 
Grove Kart GILBERT was one of the most 
eminent geologists of the world. As he was a 
native of Rochester and an honorary member 
of this society, the Academy of Science has 
special pride in his life and work. 
Dr. Gilbert was born in Rochester, May 6, 
1843. His father was the well-known portrait 
painter, Grove Sheldon Gilbert. For many 
years the family lived in the little house at the 
intersection of Culver Road and Merchants 
Road, but Karl was not born there. He had 
six brothers and sisters. The usual want of 
thrift and acquisitiveness in men of the artistic 
temperament held in the case of the father, 
and it appears that the family was poor and 
that Karl had to obtain some help for his 
course in college. He graduated as Bachelor 
of Arts at the university in 1862. 
Following his graduation he taught for one 
year as principal of the schools in Jackson, 
Mich. He then returned to Rochester and 
until 1868 was assistant to Henry A. Ward. 
This work on the geologic and zoologie mate- 
rial of Ward’s establishment probably deter- 
mined his future scientific career. Many 
thousands of the labels in the University Geo- 
logical Museum, which was the famous Ward 
collection, carry the pen-work of young Gil- 
bert. 
In 1869 he began, on the Ohio Geological 
Survey, under Professor J. S. Newberry, his 
geologic work. That this work was deliberate 
choice appears from the “ Historical Sketch ” 
by Newberry, in the report for 1869 (page 9), 
where we read: 
Of the other members of the corps, Messrs. Gil- 
bert and Sherwood were geologists who had de- 
voted much time to practical geology in New York 
and Pennsylvania, and who, for the purpose of 
adding to their experience, volunteered their serv-
