Albert Einstein was born in 1879 in Ulm, Germany. He was the first child born to Hermann and Pauline Einstein. Though he attended school as a young boy, he also received instruction at home on Judaism and violin. By the age of twelve he had taught himself geometry. At the age of sixteen he failed an exam in order to qualify to train as an electrical engineer. He remained in school and developed anew plan for his future. Einstein decided to study math and physics so he could become a teacher. Einstein thought he would be good at this because he could think mathematically and abstractly while lacking imagination and practicality. In 1896 he renounced his German citizenship.
