He was a a Scottish botanist who helped make the Cell Theory.
It was in 1828 in Scotland at Roberts laboratory.
One day Robert was bored out of his mind and had nothing to work on. So he decided to look into cell and see what is a cell made of.
Robert goes to get some samples to use to look in the microscope. He puts one of the slides in the microscope and looks at the cells really carefully. After a couple of minutes observing he finds something no one else has found. He decide to call it a nucleus.
And that is how he became famous and help make the Cell Theory.
