Background
He was born on May 3, 1825 in Gottingen, Hanover, Germany, the eldest of the five children of Georg Fridrich Seidensticker. His father (1797 - 1862) was an influential and highly respected lawyer, a veteran of the Napoleonic wars, in which he had fought on both the French and the Austrian side. As the most prominent of the leaders of the liberal political movement in Hanover, he was arrested for his part in the so-called uprising at Gottingen on January 8, 1831, and after legal proceedings had dragged on for seven years, was finally sentenced to life-imprisonment and remanded to prison at Celle. This family calamity left a deep mark on the character of the son, depriving him of a normally carefree youth and making him reserved, serious, and resolute. His mother maintained the family by conducting a private school.
In 1845 his father was released on condition that he emigrate at once, without seeing friends or family, to the United States. He landed at New York, where various German societies welcomed him with banquets, gifts, and speeches. He lived the rest of his life in Philadelphia as a journalist, accountant, and, finally, an official of the customs house.
