Rosa Smith was born on October 7, 1858, in
Monmouth, Illinois, the youngest of Lucretia (Gray) and Charles Kendall Smith's nine children. Smith's parents, originally from
Vermont, had moved to
Illinois to begin publishing a newspaper. Charles Kendall Smith founded the
Monmouth Atlas in 1846, but sold it in 1857. Seeking a warmer climate for family health reasons, the Smiths moved to
California in 1876 and settled in
San Diego. Smith completed her secondary education at the Point Loma Seminary in San Diego. Smith also attended a five-week course at a business college in
San Francisco, where she was one of only two women in the class. (The other was
Kate Sessions, later an important San Diego horticulturalist known as the "Mother of Balboa Park.") Smith had a lifelong interest in natural history. She began by observing and collecting bird and animal specimens in California and joined the San Diego Society of Natural History (
San Diego Natural History Museum) in 1878 as an associate member. Smith met
David Starr Jordan, a noted
ichthyologist from
Indiana University in
Bloomington, Indiana, while he was visiting San Diego in 1879. The circumstances of their meeting are uncertain, but Jordan may have heard Smith read her paper at a meeting of the San Diego Society of Natural History about a new species of fish. At about this time, she had discovered the
blind goby Othonops eos living in caves underneath the
Point Loma peninsula. Jordan was impressed and encouraged her to continue her studies as one of his zoology students at IU. Smith accepted Jordan's offer, and spent the summer of 1880 touring
Europe with Jordan and some of his colleagues and students. After returning to the United States, she spent two years studying at IU before an illness in the family caused her to return to San Diego in 1882 without earning an
undergraduate degree. ==Marriage and family==
