Paul A. Smith
Paul Althaus Smith (May 18, 1900June 13, 1980) was an American mathematician. His name occurs in two significant conjectures in geometric topology: the Smith conjecture, which is now a theorem, and the Hilbert–Smith conjecture, which was proved in dimension 3 in 2013. ''Smith theory'' is a theory about homeomorphisms of finite order of manifolds, particularly spheres. Smith was a student of Solomon Lefschetz at the University of Kansas, moving to Princeton University with Lefschetz in the mid-1920s. He finished his doctorate at Princeton, in 1926. His Ph.D. thesis was published in the ''Annals of Mathematics'' that same year. He also worked with George David Birkhoff, with whom he wrote a 1928 paper in ergodic theory, entitled ''Structure analysis of surface transformations'', which appeared in the ''Journal des Mathématiques''. He subsequently became a professor at Columbia University and at Barnard College. His students at Columbia included Sherman K. Stein and Moses Ri ...

Suzanne Bloch (August 9, 1907 – January 29, 2002) was a Swiss-American musician and an influential pioneer of Early Music Revival during the 20th century. Biography Suzanne Bloch was born in Geneva in 1907 into the family of composer Ernest Bloch. The family moved to New York in 1916 when Ernst Bloch took on teaching and conducting responsibilities there. She went to Paris to study music with Nadia Boulanger Juliette Nadia Boulanger (; 16 September 188722 October 1979) was a French music teacher, conductor and composer. She taught many of the leading composers and musicians of the 20th century, and also performed occasionally as a pianist and organis ... in 1925, and decided to become a lute player after hearing an early-music concert. She went on to study music in Paris and Berlin, and she met Arnold Dolmetsch in England in 1933. Dolmetsch sold her a lute from 1600 that he had restored himself.

Early Music
Early music generally comprises Medieval music (500–1400) and Renaissance music (1400–1600), but can also include Baroque music (1600–1750) or Ancient music (before 500 AD). Originating in Europe, early music is a broad Dates of classical music eras, musical era for the beginning of Classical music, Western classical music. Terminology Interpretations of historical scope of "early music" vary. The original Academy of Ancient Music formed in 1726 defined "Ancient" music as works written by composers who lived before the end of the 16th century. Johannes Brahms and his contemporaries would have understood Early music to range from the High Renaissance and Baroque, while some scholars consider that Early music should include the music of ancient Greece or Music of ancient Rome, Rome before 500 AD (a period that is generally covered by the term Ancient music). Music critic Michael Kennedy (music critic), Michael Kennedy excludes Baroque, defining Early music as "musical composi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moses Richardson
In Abrahamic religions, Moses was the Hebrew prophet who led the Israelites out of slavery in the Exodus from Egypt. He is considered the most important prophet in Judaism and Samaritanism, and one of the most important prophets in Christianity, Islam, the Baháʼí Faith, and other Abrahamic religions. According to both the Bible and the Quran, God dictated the Mosaic Law to Moses, which he wrote down in the five books of the Torah. According to the Book of Exodus, Moses was born in a period when his people, the Israelites, who were an enslaved minority, were increasing in population; consequently, the Egyptian Pharaoh was worried that they might ally themselves with Egypt's enemies. When Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population of the Israelites, Moses' Hebrew mother, Jochebed, secretly hid him in the bulrushes along the Nile river. Pharaoh's daughter discovered the infant there and adopted him as a foundling, thus he gre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
