Rizal went to study ophthalmology in Europe, first in Paris where he assisted a leading ophthalmologist and befriended painter Juan Luna, then in Heidelberg, Germany where he studied under a distinguished ophthalmologist and befriended Professor Ferdinand Blumentritt. He spent time in Leipzig and Dresden before settling in Berlin, where he worked as an assistant to a famous ophthalmologist, attended lectures at the university, and published his novel Noli Me Tangere. However, in the winter of 1886 Rizal lived in extreme poverty in Berlin with barely any money and only one meal a day.
