Einstein was born on March 14, 1879, to a Jewish family, in Ulm, Württemberg, Germany. His father was hermann einstein, a salesman who later ran an electro-chemical works, and his mother was pauline née koch. albert einstein was 8 pounds and 3 ounces and he was born at home. At his birth, albert's mother was reputedly frightened that her infant's head was so large and oddly shaped. though the size of his head appeared to be less remarkable as he grew older, it's evident from photographs of Einstein that his head was disproportionately large for his body throughout his life. His parents also worried about his intellectual development as a child due to his initial language delay and his lack of fluency until the age of nine, though he was one of the top students in his elementary school.
