Question:
Augusta Ada King-Noel, Countess of Lovelace (nee Byron; 10 December 1815 - 27 November 1852) was an English mathematician and writer, chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation, and published the first algorithm intended to be carried out by such a machine. As a result, she is sometimes regarded as the first to recognise the full potential of a "computing machine" and the first computer programmer. Ada Lovelace was the only legitimate child of the poet Lord Byron, and his wife Anne Isabella "Annabella" Milbanke, Lady Wentworth.
In her notes, Lovelace emphasised the difference between the Analytical Engine and previous calculating machines, particularly its ability to be programmed to solve problems of any complexity. She realised the potential of the device extended far beyond mere number crunching. In her notes, she wrote: [The Analytical Engine] might act upon other things besides number, were objects found whose mutual fundamental relations could be expressed by those of the abstract science of operations, and which should be also susceptible of adaptations to the action of the operating notation and mechanism of the engine...Supposing, for instance, that the fundamental relations of pitched sounds in the science of harmony and of musical composition were susceptible of such expression and adaptations, the engine might compose elaborate and scientific pieces of music of any degree of complexity or extent. This analysis was an important development from previous ideas about the capabilities of computing devices and anticipated the implications of modern computing one hundred years before they were realised. Walter Isaacson ascribes Lovelace's insight regarding the application of computing to any process based on logical symbols to an observation about textiles: "When she saw some mechanical looms that used punchcards to direct the weaving of beautiful patterns, it reminded her of how Babbage's engine used punched cards to make calculations." This insight is seen as significant by writers such as Betty Toole and Benjamin Woolley, as well as the programmer John Graham-Cumming, whose project Plan 28 has the aim of constructing the first complete Analytical Engine. According to the historian of computing and Babbage specialist Doron Swade: Ada saw something that Babbage in some sense failed to see. In Babbage's world his engines were bound by number...What Lovelace saw--what Ada Byron saw--was that number could represent entities other than quantity. So once you had a machine for manipulating numbers, if those numbers represented other things, letters, musical notes, then the machine could manipulate symbols of which number was one instance, according to rules. It is this fundamental transition from a machine which is a number cruncher to a machine for manipulating symbols according to rules that is the fundamental transition from calculation to computation--to general-purpose computation--and looking back from the present high ground of modern computing, if we are looking and sifting history for that transition, then that transition was made explicitly by Ada in that 1843 paper.

Question:
Bill "Bojangles" Robinson (May 25, 1878 - November 25, 1949) was an American tap dancer and actor, the best known and most highly paid African-American entertainer in the first half of the twentieth century. His long career mirrored changes in American entertainment tastes and technology. He started in the age of minstrel shows and moved to vaudeville, Broadway, the recording industry, Hollywood, radio, and television.
In 1928, a white impresario, Lew Leslie, produced Blackbirds of 1928 on Broadway, a black revue for white audiences starring Adelaide Hall and Bill Robinson along with Aida Ward, Tim Moore and other black stars. The show was a huge success on Broadway, where it ran for over one year to sell-out performances. On stage, Adelaide Hall and Robinson danced and sang a duet together, which captivated the audiences. From then on, Robinson's public role was that of a dapper, smiling, plaid-suited ambassador to the white world, maintaining a connection with the black show-business circles through his continuing patronage of the Hoofers Club, an entertainer's haven in Harlem. So successful was Adelaide Hall's collaboration with Bojangles, they even appeared together on stage at the prestigious Palace Theatre (Broadway) before they were teamed up together again by Marty Forkins (Robinson's manager) to star in another Broadway musical titled, "Brown Buddies", that opened in 1930 at the Liberty Theatre, where it ran for four months before commencing a road tour of the States. In 1939, Robinson returned to the stage in The Hot Mikado, a jazz version of the Gilbert and Sullivan operetta. The show opened at the Broadhurst Theatre, with Robinson cast in the role of the Emperor. His rendition of My Object All Sublime stopped the show and produced eight encores. After Broadway, the show moved to the 1939 New York World's Fair, and was one of the greatest hits of the fair. August 25, 1939, was named Bill Robinson Day at the fair. Robinson's next Broadway show, All in Fun (1940), was with an all-white cast. Despite having Imogene Coca, Pert Kelton, and other stars, the show received poor reviews at out-of-town tryouts in New Haven and Boston. When the white stars and co-producers, Phil Baker and Leonard Sillman, withdrew, Robinson became the star, the first time an African-American headlined an otherwise all-white production. Although the reviewers were enthusiastic about Robinson, they panned the show, and it failed to attract audiences. All in Fun closed after four performances.
