Lorentz studied physics and mathematics at the University of Leiden, where he was strongly influenced by the teaching of astronomy professor Frederik Kaiser it was his influence that led him to become a physicist. From 1866-1869 he attended the newly established high school in Arnhem, and in 1870 he passed the exams in classical languages which were then required for admission to University. In 1862, after his mother's death, his father married Luberta Hupkes.
