Der Struwwelpeter (1845; or Shockheaded Peter) is a German children's book by Heinrich Hoffmann.
 It comprises ten illustrated and rhymed stories, mostly about children.
 Each has a clear moral that demonstrates the disastrous consequences of misbehavior in an exaggerated way.
 The title of the first story provides the title of the whole book.
 "Der Struwwelpeter" is one of the earliest books for children that combines visual and verbal narratives in a book format, and is considered a precursor to comic books.
Shock Headed Peters were a British post-punk band, formed in 1982.
 The band took their name from the 19th-century German's children book "Der Struwwelpeter" ("Shockheaded Peter") by Heinrich Hoffmann.
Alfredo "Chacho" Vega (born February 2, 1935 in San Lorenzo, Paraguay - died February 14, 2012 in San Lorenzo, Paraguay) is a retired Paraguayan footballer who played for clubs of Paraguay, Brazil, Chile and Colombia.
Germán Cueto (born Mexico City, February 8 or 9, 1883 – died February 14, 1975) was a Mexican artist.
 He was part of the initial wave of artistic activity following the Mexican Revolution.
 However, his stay in Europe from 1927 to 1932 moved him into more European and more abstract work, especially sculpture.
 While he had a number of exhibitions in Mexico during his life including a retrospective at the Museo de Arte Moderno in 1965, he did not have the kind of success that many of his contemporaries did as he did not follow the then dominant themes or styles of Mexican muralism movement.
 His work was considered to be avant-garde and is considered to be the first Mexican abstract artist, creating masks and sculptures of wood, wire, plastic, sheet metal, ceramic, electrical wire and other materials, traditional and non-traditional.

 He died February 19, 1981 at the New England Medical Center.
 His wife died February 8 of that year.
 The Warren McGuirk Alumni Stadium at UMass is named in his honor.
