Question: Patty Hill is perhaps best known for co-writing, with her sister Mildred Hill a song that was translated into how many languages ?

 According to the 1998 "Guinness World Records", "Happy Birthday to You" is the most recognized song in the English language, followed by "For He's a Jolly Good Fellow". "Happy Birthday to You", more commonly known as simply "Happy Birthday", is a song that is traditionally sung to celebrate the anniversary of a person's birth.  The song's base lyrics have been translated into at least 18 languages.  The melody of "Happy Birthday to You" comes from the song "Good Morning to All", which has traditionally been attributed to American sisters Patty and Mildred J. Hill in 1893, although the claim that the sisters composed the tune is disputed. <SEP> Yellow Tanabe (田辺イエロウ , Tanabe Ierou , born June 13, 19??  in Tokyo) is a Japanese manga artist.  She was an assistant for Mitsuru Adachi and Makoto Raiku and made her debut in 2002 with the short story "Lost Princess".  She is best known for the manga series "Kekkaishi", which has been adapted as an anime television series and translated into many languages.  She published a one-shot story in the inaugural issue of the revival of "Monthly Shōnen Sunday" in May 2009. <SEP> The "Harry Potter" series of fantasy novels by J. K. Rowling have become some of the most widely read works of children's literature in history, with readers of all ages and in many countries.  In April 2011 worldwide sales of Harry Potter books were estimated to be about 450 million copies.  Oddly enough, it has been difficult to accurately determine with any degree of certainty exactly how many languages Harry Potter has been translated into.  As best as can be determined (as of 2017), The Philosopher's Stone has been officially translated from the original English into 73 other languages.  A 74th language, Scots, was announced on 2017-06-28 and it is expected to be available in October, 2017.  Both Bloomsbury's and J.K. Rowling's sites have recently stated that the books have been translated into 79 languages (80 with the 2017-06-28 announcement of Scots); however, it has been argued that number actually represents the number of authorized translations (of The Philosopher's Stone) plus the original English.  The number of authorized translations is not equal to the number of languages because there have been multiple authorized translations into the same language.  Specifically, there have been two separate translations into each of: Mandarin Chinese, Portuguese, Romanian, Russian and Turkish (5 languages).  English is often included in the list of translations even though technically it should not be (indeed, it is why our list here counts up to 74).  Thus: 79 − English − 5 double-translations = 73.  It is also worthwhile to emphasize that not all seven books are have been translated into these 73 languages. <SEP> Patty Smith Hill (March 27, 1868 – May 25, 1946) was a composer and teacher who is perhaps best known for co-writing, with her sister Mildred Hill, the tune which later became popular as "Happy Birthday to You".  She was an American nursery school, kindergarten teacher, and key founder of the National Association for Nursery Education (NANE) which now exists as the National Association For the Education of Young Children (NAEYC).
