List of Women's PGA Championship champions
The Women's PGA Championship is an annual golf competition held in June, and is conducted by the Professional Golfers Association of America (PGA).
 The event was established in 1955, and is one of the five women's major championships played each year; the others are the ANA Inspiration, the U.S. Women's Open, the Women's British Open, and the Evian Championship.
 This event has always been conducted in stroke play competition, and is always the second women's major of the year.
 The first year was played with three rounds of stroke play and a final round of match play to determine the final places (36 holes for the championship, 18 holes for other matches) in order to distribute prize money.
 The trophy, formally known as the "LPGA Championship Trophy" is presented to the champion every year, with each recipient being awarded a replica of the trophy to keep.
The Miracle (1959 film)
The Miracle is a 1959 film directed by Irving Rapper and starring Carroll Baker and Roger Moore.
 It is a remake of the 1912 hand-colored, black-and-white film "The Miracle", which was in turn a production of the 1911 pantomime play "The Miracle" written by Karl Vollmöller and directed by Max Reinhardt.
South Pacific air ferry route in World War II
The South Pacific air ferry route was initially established in the 1920s to ferry United States Army Air Service aircraft to the Philippines.
 As the Japanese threat in the Far East increased in 1940, General Douglas MacArthur planned that in the event of war, the United States Army Air Corps would play a major role in defending the Philippines.
 The reinforcement by the Air Corps of forces in the Philippines, and later Allied forces in Australia, became the basis for developing the South Pacific air ferry route used during World War II.
Taishō Katsuei
Taishō Katsuei (大正活映 ) was a Japanese film studio active in the early 1920s.
 Founded in April 1920 by Ryōzō Asano, the son of zaibatsu head Sōichirō Asano, it was mostly known as Taikatsu for short.
 Its origins can be traced back to Tōyō Film (also known as the "Sunrise Film Manufacturing Company"), a venture started in 1918 by Benjamin Brodsky and Thomas Kurihara, that Asano ended up supporting.
 With Kurihara as the main director and Jun'ichirō Tanizaki as the literary consultant, Taikatsu was one of two studios founded in 1920 (the other being Shōchiku Kinema) that publicly announced their intention to make "pure films" in line with the Pure Film Movement.
 It established an actors school and began production with "Amateur Club", a film directed by Kurihara and scripted by Tanizaki that was strongly influenced by American cinema.
 Other important works include "A Serpent's Lust", another Kurihara-Tanizaki collaboration based on the same story as "Ugetsu" by Kenji Mizoguchi.
 The Taikatsu studio was located in Yokohama, below the Bluff and the Foreigner's Cemetery (a memorial tablet currently marks the site).
 Taikatsu did not last long, since it did not have enough theaters to recoup the costs of production and of importing American films.
 Its production division was taken over by Shōchiku in 1922, even though the company lasted a few more years as an exhibition business.
 A number of important film figures emerged from Taikatsu, including the directors Tomu Uchida and Buntarō Futagawa and the actors Tokihiko Okada, Ureo Egawa and Atsushi Watanabe.
Max Reinhardt
Max Reinhardt (September 9, 1873 – October 30, 1943) was an Austrian-born American theatre and film director, intendant, and theatrical producer.
 With his innovative stage productions, he is regarded as one of the most prominent directors of German-language theatre in the early 20th century.
 In 1920, he established the Salzburg Festival with the performance of Hofmannsthal's "Jedermann".
Prince Matchabelli
Prince Matchabelli is a perfume line.
 It was first designed by Prince Georges V. Matchabelli who was an amateur chemist.
 Georges Matchabelli was a Georgian prince and Georgian ambassador to Italy, but fled the Soviet Union and emigrated to the United States after the Russian Revolution.
 In New York City he and his wife, Princess Norina Matchabelli (an actress whose stage name was Maria Carmi), opened a small antiques shop, "Le Rouge et le Noir", at 545 Madison Avenue.
 The name came from Stendhal's novel of that name, which they interpreted as the red for the aristocracy for him and black for the religious (The Miracle, a famous religious play in which Norina had starred).
 (Stendhal's interpretation of the names was somewhat different: the only two choices open to his hero, Julien Sorel, a poor man for career glory and advancement—red for military and black for clergy.)
 They later established the Prince Matchabelli Perfume Company in 1926.
 Perfumes were personally blended for clients by Prince Matchabelli.
 The first three perfumes were Princess Norina, Queen of Georgia and Ave Maria.
 The company became known for the many color-coded, crown-shaped bottles designed by Norina after the Matchabelli crown and introduced in 1928 with labels on the underside.

Afterlife (play)
Afterlife is a 2008 play by Michael Frayn.
 It tells the life and career of Austrian theatrical director and actor Max Reinhardt, from the revival of the Salzburg Festival in 1920, which he helped to re-establish, until his death in New York in 1943.
 It draws from Hugo von Hofmannsthal's 1911 play Jedermann (based on the sixteenth-century English morality play, Everyman), which Reinhardt directed at the Salzburg Festival for many years following its revival in 1920.
Betty Compson filmography
This page has most if not all of Betty Compson's known film appearances 1915–48.
 Films from 1915 to 1919 are shorts, mostly for Al Christie unless otherwise stated.
 A big breakout came in 1919 with "The Miracle Man" now lost.
 In the early-to-mid 1920s Compson was a major player at Paramount with her name above the title of her films.
 By the end of the decade she was free-lancing and appearing as feature and support with name below the title of the film.
 Her star definitely took a fall somewhere after marrying director James Cruze, and she would remain a feature support into the sound era for the rest of her film career.
