Rudolph Jacob Camerarius

Today is the anniversary of the death of Rudolph Jacob Camerarius, the botanist who demonstrated the existence of sexes in plants. He died in 1721.

Camerarius was born in Germany. He was a professor of natural philosophy.
He identified and defined the male parts of the flower as the anther, and he did the same for the female part; the pistol. And, he figured out that pollen made production possible. His work was recorded for the ages in a letter he wrote to a peer in 1694 called On the sex of plants.
