Karl Heinrich Marx was born on May 5th 1818 in Tier. He was one of four siblings and as the only son; he was his father's favorite. His father, Heinrich, was married to a Dutch Jewess named Henrietta Pressburg. Heinrich was a Jewish Lawyer that had a firm belief in Judaism (http://www.historyguide.org/intellect/marx.html). It wasn't until 1838 he converted his whole family to Christianity due to the fear of the loss of his practice in the Prussian state. It wasn't an easy change for him. It took the loss of his mother in order for him to sever all ties with their native beliefs. Despite his parent's dispute with their recent conversion Karl had an untroubled childhood and a very strong background. His father always knew that one day his son would help aid all humanity in its effort to survive, "His "Splendid natural gifts" awakened in his father the hope that one day they would one day be used in the service of humanity, whilst his mother declared him to be a child of fortune in whose hands everything would go well." (The Story of His Life, Mehring, page 2) This theory of his father started to shine when Karl was in high school. It all started when Marx was asked to write a paper on a chosen profession. Marx felt that this was unfair, and that he should take a different approach. In his paper he said that there is no way that a person could choose a single profession. A person has an occupation or profession due to certain circumstances. For instance a person would have more of a chance taking an aristocratic job coming from a rich environment than a person from a much poorer background would. .
He graduated high school in 1835 to enroll at the University of Bonn to study law. While at Bonn, Jenny Von Westphalen won his heart and he asked her to marry him (Karl Marx, Compton's Encyclopedia). This was not a traditional engagement, because Karl didn't ask for her father's permission. Jenny was the daughter of an upperclassmen Ludwig Von Westphalen and the childhood friend of Sophie Marx, Karl's oldest sister.
