Japan's First Water Clock

An emperor measures time with flowing water

In the imperial capital of Otsu, Emperor Tenji of Japan introduced the Rokoku, a water clock that marked a revolution in how the Japanese measured time. The clepsydra, which used the steady flow of water to mark the passing hours, was installed as an instrument of state, regulating the rhythms of court life and governance. This innovation, adopted from Chinese and Korean models, demonstrated Japan's eagerness to embrace advanced technology and systematize its rapidly modernizing society.

Frederick Loewe Was Born

Broadway's greatest melodist enters the world

In Berlin, Frederick Loewe was born -- the Austrian-American composer who would create some of the most beautiful melodies in the history of musical theater. His partnership with lyricist Alan Jay Lerner produced 'My Fair Lady,' 'Camelot,' 'Brigadoon,' and 'Gigi' -- shows whose songs became standards that defined the sound of the American musical. From 'I Could Have Danced All Night' to 'The Rain in Spain,' Loewe's music achieved a rare alchemy of sophistication and popular appeal.
