Gregor Mendel is considered the father of genetics. He gave a lecture and published his findings on pea plants around 1865. He was an abbot and about a year later he was promoted so that he he wasn’t able to continue his experiments. Unfortunately, his paper on his research was published in a paper that very few people in the field read and the few that did read it didn’t accept such new ideas. It wasn’t until 1901 when three separate botanists ‘rediscovered’ his findings and they all noted that Mendel figured it out first.
