Rudolf Jakob Camerarius

German Physician and Botanist

Rudolf Jakob Camerarius, a German physician and botanist, made significant contributions to the field of botany. According to Austrian historian of science Josef Schultes, Camerarius was the first scientist to scientifically prove the existence of sex differences in plants and develop a method for describing these differences.

Professor and Director of the Botanical Garden in Tübingen

1687-Present

In 1687, Camerarius was appointed professor of medicine and botany and director of the botanical garden in Tübingen. During his tenure, he conducted groundbreaking research on plant physiology.

"De Sexu Plantarum Epistola"

1694

In 1694, Camerarius published his seminal work, "De Sexu Plantarum Epistola," in which he conclusively demonstrated the existence of sexes in plants and the significance of flowering as a fertilizing male element. His experiments proved that removing stamens from flowers prevented seed formation, leading him to conclude that stamens were male sex organs, pollen was the fertilizing element, and pistils were female sex organs. He attributed the role of pollen transfer to the wind.

Influence on Carl Linnaeus's Classification System

1735

Camerarius's theory of plant sexual reproduction profoundly influenced Carl Linnaeus's sexual classification system for plants, introduced in 1735. Linnaeus's system, widely used in the 18th and 19th centuries, incorporated the sex characteristics of plants and essentially expanded upon Camerarius's teachings.

Commemoration by Linnaeus

1753

In honor of Camerarius's groundbreaking work, Linnaeus named a genus of plants in the Apocynaceae family "Cameraria" in 1753.
