user: Do you think depression ran in Wittgenstein's family?

assistant: <think>
Born in Vienna into one of Europe's richest families, Ludwig Wittgenstein inherited a fortune from his father in 1913. Before World War I, he "made a very generous financial bequest to a group of poets and artists chosen by Ludwig von Ficker, the editor of Der Brenner, from artists in need. These included Trakl as well as Rainer Maria Rilke and the architect Adolf Loos." Later, in a period of severe personal depression after World War I, he gave away his remaining fortune to his brothers and sisters. Three of his four older brothers died by separate acts of suicide. Wittgenstein left academia several times: serving as an officer on the front line during World War I, where he was decorated a number of times for his courage; teaching in schools in remote Austrian villages, where he encountered controversy for using sometimes violent corporal punishment on girls and a boy (the Haidbauer incident) especially during mathematics classes; working during World War II as a hospital porter in London, notably telling patients not to take the drugs they were prescribed; and working as a hospital laboratory technician at the Royal Victoria Infirmary in Newcastle upon Tyne. He later expressed remorse for these incidents, and spent the remainder of his life lecturing and attempting to prepare a second manuscript for publication, which was published posthumously as the hugely influential Philosophical Investigations.</think>
Depression is a mental health issue which can sometimes lead to suicide. It is known to run in families. Ludwig Wittgenstein personally experienced at least one period of severe depression and three of his four older brothers died by separate acts of suicide. Based on the fact that so many of Wittgenstein's immediate family members experienced depression or died by suicide, I think it is fair to say depression ran in Wittgenstein's family.

Tiergartenstraße is a street in the Tiergarten district in central Berlin, the capital of Germany. The street runs east-west along the southern edge of the Großer Tiergarten park from Kemperplatz and Ben-Gurion-Straße near Sony Center and Potsdamer Platz in the east to the intersection of Hofjägerallee and Klingelhöferstraße in the west. On the street’s southern side, the street intersects with (from east to west), Herbert-von-Karajan-Straße, Stauffenbergstraße, Hildebrandstraße, Hiroshimastraße and Clara-Wieck-Straße.The neighbourhood was incorporated into the City of Berlin in 1861, soon after the 1871 Unification of Germany it developed into an affluent residential area and later into the capital's diplomatic quarter.The Kemperplatz at the eastern end formerly marked the starting point of the Siegesallee boulevard running northwards through the park to Königsplatz in front of the Reichstag. On Tiergartenstaße No. 1 is the Berlin Musical Instrument Museum and the adjacent building of the Berliner Philharmonie behind it, a major centre for musical performances.On the western corner on Tiergartenstraße No. 6 is the Berlin Museum of Applied Art and next to it the Berlin Art Library, both part of the Kulturforum cluster of the Berlin State Museums. On the intersection with Stauffenbergstraße on No. 12 is the Austrian embassy, erected in 2001 according to plans designed by Hans Hollein. Further diplomatic missions follow: the Indian and South African embassies (on No. 18) as well as the Italian and Japanese representations at the corner of Hiroshimastraße, both as former Axis powers located at vast buildings from about 1941/42 that have been reconstructed after World War II. A number of other embassies are located along nearby streets.At the western end of Tiergartenstraße are the Jesuit Canisius-Kolleg gymnasium in the building of the former Krupp representative office on No. 30, the Saudi Arabian embassy and finally the offices of the Christian Democratic Konrad Adenauer Foundation. On the corner of Klingelhöferstraße is a sculpture depicting Konrad Adenauer and Charles de Gaulle shaking hands, symbolising their role in overcoming the centuries-long French–German enmity and laying the groundwork for the Franco–German Friendship after World War II.On the north side of Tiergartenstraße just west of Stauffenbergstraße is a large seated statue of the composer Richard Wagner in the Tiergarten park. A glass canopy has been erected over the statue to protect it from the elements.The bus terminal at the corner Herbert-von-Karajan-Straße was formerly the site of the villa Tiergartenstraße No. 4, the headquarters of the Nazi \euthanasia\" program (the mass murder of disabled people and others)</think>
