In 1805, Heinrich died by drowning in a canal by their home in Hamburg. Although it was possible that his death was accidental, his wife and son believed that it was suicide because he was very prone to unsociable behavior, anxiety and depression which became especially pronounced in his last months of life. Arthur showed similar moodiness since his youth and often acknowledged that he inherited it from his father; there were also several other instances of serious mental health issues on his father's side of the family. His mother Johanna was generally described as vivacious and sociable. Despite the hardships, Schopenhauer seemed to like his father and later always mentioned him in a positive light. Heinrich Schopenhauer left the family with a significant inheritance that was split in three among Johanna and the children. Arthur Schopenhauer was entitled to control of his part when he reached the age of majority. He invested it conservatively in government bonds and earned annual interest that was more than double the salary of a university professor.
