During the first 30 years of The American Society of Mammalogists (ASM
), a small but notable group of women made significant contributions t
o the Society and to mammalogy in general. The limited opportunity for
women in mammalogy at the time of the founding of the ASM in 1919 is
evidenced by the observation that only 16 of 435 Charter Members were
women. To highlight the contributions of early women mammalogists, we
describe the accomplishments of 23 women in short biographical treatme
nts. To facilitate our presentations of activities and accomplishments
, each woman was placed into one of six categories, although some indi
viduals could have been listed under more than one category. The six c
ategories were research in the field, research in the museum, research
in the laboratory, service to the ASM, other naturalists involved in
the ASM, and relevant nonmembers.
