Life

Jantine Tammes attended girls' middle school from 1883 . With this training, it was not possible for her to take up university studies, and the admission quotas for girls to high schools were limited. Therefore, she initially took private lessons in the natural sciences. In 1890 Jantine Tammes went to the University of Groningen . Women were allowed to study there, but they were not admitted to the exam. In 1896, Tammes and two other students founded the Walking Club , the oldest student association in the Netherlands. In 1898 the club was renamed the Groningen Female Student Society , in 1912 it was named Magna Pete . Jantine Tammes passed a teacher certificate for physics , geography and chemistry in 1892 , and in 1897 she acquired another for botany , zoology , mineralogy and geology . Jantine Tammes initially earned her living as a teacher at a girls' middle school. As a result, she took an assistant position at JW Molls, who was professor of botany at the University of Groningen. He arranged for her to do research in the laboratory of the plant geneticist Hugo de Vries in Amsterdam . Jantine Tammes was able to deepen her knowledge of evolution and genetics there .

Back in Groningen, she did research on these topics and developed de Vries' genetic experiments further. The university also entrusted her with the supervision of the student botanical internships. Due to a wide-ranging campaign by Moll and expert support from renowned botanists, Jantine Tammes received an extraordinary professorship for variability and inheritance in 1919 . She remained in this position until her retirement in 1937.

Scientific work

Jantine Tammes contributed essential knowledge of plant genetics . In her specialist article The behavior of fluctuatingly varying traits in hybridization , published in 1911 , she demonstrated that the multiple-factor hypothesis can explain the inheritance of continuous traits. Although her scientific work surpassed that of her colleague Nilsson-Ehle , and she also provided more experimental data as evidence, her findings in the history of botany were ascribed to her colleague.

Appreciation

The University of Groningen awarded Jantine Tammes an honorary doctorate in 1912 for her contribution to plant genetics .
