Hans Albert Einstein
Hans Albert Einstein was born on May 14, 1904 in Bern, Switzerland, where his father, Albert Einstein, worked as a clerk in the patent office. His father was of German-Jewish descent and his mother, Mileva Marić, Serbian-Orthodox. His younger brother, Eduard Einstein, was born in 1910 and died in 1965. The fate of his older sister, Lieserl Einstein, Albert Einstein's and Mileva Marić's first child, is unknown. Their parents divorced in 1919 after living apart for five years.

Einstein then traveled incognito to Smallville to seek out a suitable family; this required his sneaking away from fawning government handlers assigned to protect/baby-sit Einstein as a vital national resource. In the course of several days in Smallville, he encountered Jonathan and Martha Kent, and decided that they would be ideal foster parents for the Kryptonian child, due to their honest and generous natures. Through a variety of ruses, Einstein arranged for the Kents to be in the immediate area when Kal-El's spaceship landed, thus ensuring he would be found and later adopted by them.
