Gregor Johann Mendel was born in Heinzendorf, North of Moravia. His father Anton was a farmer who was crippled by a falling tree but forced to work because young Johann was sick and in bed.
Often, his father would say “He is a disappointment for me” referring to young Johann. It was hard for Johann to look at his father forcing his crippled body to work in the farm and yet he could not do anything to help him – but watch. Johann did not have a good relationship with his father Anton. The reason why Johann only spoke to his mother Rosine was because his mother was polite and sweet natured, and likewise to his younger sister Theresia who had the same temperament as his mother. He did not even talk to his older sister Veronika who was very antagonistic towards him.
At the age of eleven he was sent away from his family to finish his elementary and high school education at Gymnasium in Troppau. His parents never sent him money for his school fees because they saved their money to buy the land from their feudal lord. However, his younger sister provided him some finances for which he was greatly indebted for his entire life.
Gregor mendel graduated at the Gymnasium and moved on to the Philosophical Institute, a two-year program for all high achieving students from the high school education before they could pursue to university. Without money life was even more difficult for Johann. He felt very cold and hungry at night, but he survived because of his sister Theresia’s support. Because he was indebted to his sister Theresia he took responsibility of helping two of his nephews (sons of Theresia) on their education and who became physicians later .
