Context: John S. Clark (21 March 1885 – 1 June 1956) was a Scottish-born Australian entomologist and myrmecologist known for his study of Australian ants. Born in Glasgow, he developed an interest in entomology at a young age.  Clark first arrived in Australia in 1905 and originally worked for the state railways in Queensland.  He developed an interest in ants shortly afterwards, collecting his first specimens in North Queensland.  He married his first wife, Maggie Forbes in 1908, bearing four children, until her death in 1935.  He married his second wife, Phyllis Marjorie Claringbulls in 1939 and had two daughters with her until she committed suicide in 1943.  As a result, Clark sent his daughters to an orphanage. Peter Lupo (ca. 1535 – 1608) was an Italian viol player and composer active for 40 years or more at the court of Elizabeth I of England.  Born in Venice to Ambrose Lupo and his first wife Lucia, he and his brother Joseph first went to Antwerp, where Peter joined the musicians' guild on 20 August 1557; He married his first wife Katherine Wicke, and had his first child in Antwerp before moving to England, where Ambrose had served in the royal viol consort since 1540.  In 1567, Peter succeeded Albert of Venice, another Italian who had died on 17 January 1555.  Peter Lupo was among the musicians who played at the funeral of Queen Elizabeth in 1603.  His nephew Thomas Lupo the elder and son Thomas Lupo the younger also became court musicians.  Another son, Philip, moved to Virginia and became the founder of the American branch of the Lupo family.  Among Lupo's descendants in the United States was the Sacred Harp composer Sarah Lancaster, whose father was James Lupo Lancaster.

She is the aunt of Dorothy Gale and wife of Uncle Henry, and lives together with them on a farm in Kansas.  In "The Wonderful Wizard of Oz", she is described as having been a "young, pretty wife" when she arrived at Uncle Henry's farm, but having been "grayed" by her life there, implying that she appears older than one might expect from her chronological age.  Baum tells us that when Dorothy first came to live with her, Em would "scream and press her hand upon her heart" when startled by Dorothy's laughter, and she appears emotionally distant to her at the beginning of the story.  However, after Dorothy is restored to her at the end of the book, we see her true nature: she cries out, "My darling child!"  and covers her with kisses. Konstantin Rodko (24 August 1908 – 30 September 1995) was a Latvian painter who was based in the United States.  Rodko's parents were Belarusian and Estonian.  He married his first wife in Latvia and had four children.  During World War II they had lived in Germany until they were able to leave from Bremerhaven on 19 August 1950 on the "USS General Harry Taylor", and arrived in New York City four days later.  It was in America his painting talents came to prominence and sold them on the streets of New York.  Rodko lived in Brooklyn with his children and then divorced his first wife and remarried a woman by the name of Kate Dennison.  She too was a painter and the couple sold their works alongside each other. Grand Duke Alexei Alexandrovich of Russia,(Russian: Алексей Александрович; 14 January 1850 (2 January O.S.) in St. Petersburg – 14 November 1908 in Paris) was the fifth child and the fourth son of Alexander II of Russia and his first wife Maria Alexandrovna (Marie of Hesse).  Chosen for a naval career, Alexei Alexandrovich started his military training at the age of 7.

In 1871, he was sent as a goodwill ambassador to the United States and Japan. "When I Lost You" is a song with music and lyrics by Irving Berlin.  It was written in 1912 after his wife of five months, the former Dorothy Goetz, died of typhoid fever.  In it he poured out the grief of his loss; it was the only song that he ever admitted had such a connection to his own life.  The song, a ballad, was unlike any of Berlin's previous songs, which were upbeat tunes written to take advantage of the dance craze.  The song is in a slow waltz tempo.  It became Berlin's first hit ballad. Dorothy Goetz (February 5, 1892 – July 17, 1912) was the first wife of the famous songwriter Irving Berlin.

Der Widerspänstigen Zähmung (also: Der Widerspenstigen Zähmung ) (English: "The Taming of the Shrew") is a German-language comic opera in four acts by the German composer Hermann Goetz.  It was written between 1868 and 1872 and first performed at the National Theatre Mannheim on 11 October 1874 under the conductor Ernst Frank.  The libretto, by and the composer, is based on Shakespeare's "The Taming of the Shrew".  The style of the opera shows Goetz turning away from the musical ideas of Richard Wagner towards the classicism of Mozart.  "Der Widerspänstigen Zähmung " was a huge success, not only in Germany but in the United States and in Great Britain, where it received high praise from George Bernard Shaw. Irving Berlin (born Israel Beilin; May 11, 1888 – September 22, 1989) was an American composer and lyricist, widely considered one of the greatest songwriters in American history.

He published his first song, "Marie from Sunny Italy", in 1907, receiving 33 cents for the publishing rights, and had his first major international hit, "Alexander's Ragtime Band" in 1911.  He also was an owner of the Music Box Theatre on Broadway.
