Bochum (German pronunciation: [ˈboːxʊm]; Westphalian: Baukem) is a city in North Rhine-Westphalia (NRW), western Germany. It is located in the Ruhr area and is surrounded by the cities of Essen, Gelsenkirchen, Herne, Castrop-Rauxel, Dortmund, Witten and Hattingen. With a population of nearly 375,000, it is the 16th most populous city in Germany.

Bochum dates from the 9th century, when Charlemagne set up a royal court at the junction of two important trade routes. It was first officially mentioned in 1041 as Cofbuokheim in a document of the archbishops of Cologne. Originally, it may have meant "Brookhome" or "Bacheim" and later seems to have gained the notorious reputation of "Bookhorn" or "Horn Book". In 1321, Count Engelbert II von der Marck granted Bochum a town charter, but the town remained insignificant until the 19th century, when the coal mining and steel industries emerged in the Ruhr area, leading to the growth of the entire region. The population of Bochum increased from about 4,500 in 1850 to 100,000 in 1904. Bochum acquired city status, incorporating neighbouring towns and villages. Additional population gains came from immigration, primarily from Poland.

Herbert Grönemeyer (born April 12, 1956) is a German musician and actor, popular in Germany, Austria and Switzerland. He starred as war correspondent Lieutenant Werner in Wolfgang Petersen's movie Das Boot, but later concentrated on his musical career. His fifth album 4630 Bochum (1984) and his 20th album Mensch (Human) (2002) are the best-selling German-language records of all time.^{[citation needed]} He is the most successful artist in Germany with album sales of over 13 million albums.

Grönemeyer often refers to his personal roots as lying in the German town of Bochum where he spent most of his childhood, youth and early adulthood. Still today, the song Bochum, first released in 1984, is one of his signature songs, especially during live performances. Being born in Göttingen and not in Bochum he has his own explanation: "I was only born in Göttingen because my mother often fainted when she was pregnant with me. She did this every time she turned to her left side, and no one believed her. In Göttingen there was a professor, a specialist, and he didn't believe her either, at which point she lay down, fainted, and brought me into the world. This is why I was born in Göttingen."
