1951Arnold Schoenberg, Austrian-American composer and painter (born 1874)^[†]

Arnold Schoenberg or Schönberg was an Austrian and American composer, music theorist, teacher and writer. He was among the first modernists who transformed the practice of harmony in 20th-century classical music, and a central element of his music was its use of motives as a means of coherence. He propounded concepts like developing variation, the emancipation of the dissonance, and the "unity of musical space".

1951Vuoristorata, one of the oldest still-operating wooden roller coasters in Europe, is opened at the Linnanmäki amusement park in Helsinki, Finland.^[†]

Vuoristorata is a classic wooden roller coaster located at the Linnanmäki amusement park in Helsinki, Finland. It was built in the winter of 1950 by Linnanmäki's staff on the basis of drawings by Valdemar Lebech, a Danish builder specialising in fairground rides. The construction work was led by the Danish ride operator Svend Jarlström, who at the time owned most of Linnanmäki's rides. Opened on 13 July 1951, Vuoristorata was the largest roller coaster in the Nordic countries and the tallest in Europe at the time. Expected to last up to 15 years, it was originally designed as a temporary attraction for the amusement park, opened in 1950. One of the main reasons for its construction was to attract tourists from the 1952 Summer Olympics held in the city. Since then, its temporary status was renewed for extended periods, until it was eventually regarded as a permanent structure.
