IN: Shen Kuo (Chinese: Chen Gua ; 1031-1095), courtesy name Cunzhong (Cun Zhong ) and pseudonym Mengqi (now usually given as Mengxi) Weng (Meng Xi Weng ), was a Han Chinese polymathic scientist and statesman of the Song dynasty (960-1279). Excelling in many fields of study and statecraft, he was a mathematician, astronomer, meteorologist, geologist, zoologist, botanist, pharmacologist, agronomist, archaeologist, ethnographer, cartographer, encyclopedist, general, diplomat, hydraulic engineer, inventor, academy chancellor, finance minister, governmental state inspector, poet, and musician.

Shen Kuo was born in Qiantang (modern-day Hangzhou) in the year 1031. His father Shen Zhou (Chen Zhou ; 978-1052) was a somewhat lower-class gentry figure serving in official posts on the provincial level; his mother was from a family of equal status in Suzhou, with her maiden name being Xu (Xu ). Shen Kuo received his initial childhood education from his mother, which was a common practice in China during this period. She was very educated herself, teaching Kuo and his brother Pi (Pi ) the military doctrines of her own elder brother Xu Tang (Xu Dong ; 975-1016). Since Shen was unable to boast of a prominent familial clan history like many of his elite peers born in the north, he was forced to rely on his wit and stern determination to achieve in his studies, subsequently passing the imperial examinations and enter the challenging and sophisticated life of an exam-drafted state bureaucrat. From about 1040 AD, Shen's family moved around Sichuan province and finally to the international seaport at Xiamen, where Shen's father accepted minor provincial posts in each new location. Shen Zhou also served several years in the prestigious capital judiciary, the equivalent of a federal supreme court. Shen Kuo took notice of the various towns and rural features of China as his family traveled, while he became interested during his youth in the diverse topography of the land. He also observed the intriguing aspects of his father's engagement in administrative governance and the managerial problems involved; these experiences had a deep impact on him as he later became a government official. Since he often became ill as a child, Shen Kuo also developed a natural curiosity about medicine and pharmaceutics. Shen Zhou died in the late winter of 1051 (or early 1052), when his son Shen Kuo was 21 years old. Shen Kuo grieved for his father, and following Confucian ethics, remained inactive in a state of mourning for three years until 1054 (or early 1055). As of 1054, Shen began serving in minor local governmental posts. However, his natural abilities to plan, organize, and design were proven early in life; one example is his design and supervision of the hydraulic drainage of an embankment system, which converted some one hundred thousand acres (400 km2) of swampland into prime farmland. Shen Kuo noted that the success of the silt fertilization method relied upon the effective operation of sluice gates of irrigation canals.

IN: George Michael Cohan (July 3, 1878 - November 5, 1942), known professionally as George M. Cohan, was an American entertainer, playwright, composer, lyricist, actor, singer, dancer and producer. Cohan began his career as a child, performing with his parents and sister in a vaudeville act known as "The Four Cohans." Beginning with Little Johnny Jones in 1904, he wrote, composed, produced, and appeared in more than three dozen Broadway musicals. Cohan published more than 300 songs during his lifetime, including the standards "Over There", "Give My Regards to Broadway", "The Yankee Doodle Boy" and "You're a Grand Old Flag".

Cohan appeared in 1930 in a revival of his tribute to vaudeville and his father, The Song and Dance Man. In 1932, Cohan starred in a dual role as a cold, corrupt politician and his charming, idealistic campaign double in the Hollywood musical film The Phantom President. The film co-starred Claudette Colbert and Jimmy Durante, with songs by Rodgers and Hart, and was released by Paramount Pictures. He appeared in some earlier silent films but he disliked Hollywood production methods and only made one other sound film, Gambling (1934), based on his own 1929 play and shot in New York City. A critic called Gambling a "stodgy adaptation of a definitely dated play directed in obsolete theatrical technique." It is considered a lost film. Cohan earned acclaim as a serious actor in Eugene O'Neill's only comedy, Ah, Wilderness! (1933), and in the role of a song-and-dance President Franklin D. Roosevelt in Rodgers and Hart's musical I'd Rather Be Right (1937). The same year, he reunited with Harris to produce a play called Fulton of Oak Falls, starring Cohan. His final play, The Return of the Vagabond (1940), featured a young Celeste Holm in the cast. In 1940, Judy Garland played the title role in a film version of his 1922 musical Little Nellie Kelly. Cohan's mystery play Seven Keys to Baldpate was first filmed in 1916 and has been remade seven times, most recently as House of Long Shadows (1983), starring Vincent Price. In 1942, a musical biopic of Cohan, Yankee Doodle Dandy, was released, and James Cagney's performance in the title role earned the Best Actor Academy Award. The film was privately screened for Cohan as he battled the last stages of abdominal cancer; Cohan's comment on Cagney's performance was, "My God, what an act to follow!" Cohan's 1920 play The Meanest Man in the World was filmed in 1943 with Jack Benny.
