Klara Polzl was born in Austria in 1860. At age 16, she was working as a housekeeper for her future husband, Alois, and married him in January of 1885. Their first son, Gustav, was born 4 months later.
Daughter Ida was born in the fall of 1886. Both children died of diphtheria during the winter of 1887-1888, while still small children. Just before they died, in 1887, she had another son Otto, but he died the same year he was born - all three children dying close together.
Klara and Alois were to have two more sons and then another daughter. One of the sons, Edmond, died of the measles when he was five. So she only had two children who survived childhood, one boy and one girl.
Klara has been described by a biographer as "...a large girl, almost as tall as her husband, with dark brown hair and even features." I'm not sure what "even features" means. "Even" as opposed to "odd," I suppose. The biographer indicated Klara's adult life was spent keeping house and raising children. One would have to note that she was only marginally successful at the latter, but perhaps that's too cruel a thing to say. Alois was not all that interested in either of those things. He died in 1903 and left Klara a pension from his government job.
Klara was a devout Roman Catholic and took her children to church regularly. Four years after her husband, in 1907, at age 47, Klara also died - of iodoform poisoning, a drug used in the treatment of breast cancer. She was buried near Linz.
Now, this doesn't seem like a very important woman, I know. She had a short, rather tragic life, and didn't really accomplish that much, by most standards. Yet, the fact that Klara once lived was to affect the entire world.
You see, when she married, she took Alois' last name of course, and Alois' last name was Hitler, and the name of her surviving son was Adolf.
Update: "Adolf challenged my father to extreme harshness and got his sound thrashing every day. He was a scrubby little rogue, and all attempts of his father to thrash him for his rudeness and to cause him to love the profession of an official of the state were in vain. How often on the other hand did my mother caress him and try to obtain with her kindness where the father could not succeed with harshness ..." (Paula Hitler) Follow this link
