Whilst my admiration knows no bounds for early scientists who stuck pins into their own eyes (Isaac Newton) or scratched the pus of cow pox lesions into a small boy (Edward Jenner), I like to ponder on the less scary biography of Gregor Mendel.
(That is too flip about Jenner: he had a sound, scientific basis of knowledge when he injected the boy and his discovery has had the miraculous effect of eradicating smallpox globally).
Our curious monk (take that whichever way you please) grew and cross-bred around 28,000 pea plants between 1856 and 1863. I leave you to perform the higher arithmetic, but that's a lot of peas per annum in my estimation. Perhaps his failure to obtain teaching qualifications made him determined to continue to experiment.
From this, he deduced that traits such as colour (green or yellow) and smooth or wrinkly skins (I wish he could do something about my hair hues and facial crevasses) are inherited in discrete units (now called genes) and that some are dominant and some are recessive. He also looked at pod shape and colour, flower colour, flower position and plant height. This was thorough research and a huge finding but its importance failed to be recognised for over a hundred years.
Whatever was made of his theories later, I love to think of him, peacefully patrolling his lines of legumes in the monastery garden and jotting down their features. Calm and soothing. I'm sure he talked to them.
Yet, did he ever have nightmares?
