Johann Gregor Mendel was a priest. For a short while, he worked as a substitute high school teacher. Later he worked as a physics* high school teacher at the same local high school. Mendel spent most of his time experimenting with his pea plants, which he grew in the monastery garden. It was from cross-breeding those pea plants that he discovered genetics.

*Physics-The studies of a wide range of physical phenomena spanning all length scales from sub-atomic particles of which all ordinary matter is made (particle physics) to the behavior of the material Universe as a whole (cosmology).

July 20, 1822

January 6, 1884 (age 61 years old).

Place of birth

Known for
Gregor Mendel is known for creating the science of genetics. He learned that all living things produce offspring that carry the parents’ genes.

Science Explained
Gregor Mendel discovered genetics. He figured out from cross-breeding pea plants that offspring inherit two main genes from their parents. One comes from the mother and one from the father. If these two genes are different, the offspring takes on the stronger gene, and the other gene doesn’t have a result that is visible. Different traits reappear in in offspring in every single possible combination. Mendel cross-bred the plants and their offspring carried the parents’ traits, proving his theories correct.


1. 1847 Gregor Mendel became a priest, working and living at his monastery in Brunn.

2. 1856-1865 He started experimenting with pea plants in the monastery garden. He spent a lot of his time experimenting with genetics by cross-breeding the plants.

3. 1847-1851, 1853-1867 He worked as a high school substitute teacher at his neighborhood high school and later became a physics teacher at that same school.

4. 1868 Mendel was elected abbot of his monastery.

Nowhere did any research option state specifically where any of the jobs he worked were.

Did you know?
Here are some interesting facts about Gregor Johann Mendel:
  • As a young student, Mendel was so exceptional in his studies that he gave lessons to classmates for a fee that would go towards the family farm.
  • When Mendel was a 16, his parents were in debt and Gregor ended up supporting himself and hiring tutors.
  • Gregor Mendel couldn't pay for his own schooling, so his younger sister gave him part of her dowry (money set aside for marriage). This made him a monk because he got an education without paying for it himself.
  • During his college and further schooling years, Gregor Mendel ended up taking 5 years off from illness.
  • Mendel’s work in creating the science of genetics was not discovered until about six years after his death.
