Question: Matthew Boulton  (; 3 September 1728 - 17 August 1809) was an English manufacturer and business partner of Scottish engineer James Watt. In the final quarter of the 18th century, the partnership installed hundreds of Boulton & Watt steam engines, which were a great advance on the state of the art, making possible the mechanisation of factories and mills. Boulton applied modern techniques to the minting of coins, striking millions of pieces for Britain and other countries, and supplying the Royal Mint with up-to-date equipment.

The elder Boulton's business prospered after young Matthew's birth, and the family moved to the Snow Hill area of Birmingham, then a well-to-do neighbourhood of new houses. As the local grammar school was in disrepair Boulton was sent to an academy in Deritend, on the other side of Birmingham. At the age of 15 he left school, and by 17 he had invented a technique for inlaying enamels in buckles that proved so popular that the buckles were exported to France, then reimported to Britain and billed as the latest French developments.  On 3 March 1749 Boulton married Mary Robinson, a distant cousin and the daughter of a successful mercer, and wealthy in her own right. They lived briefly with the bride's mother in Lichfield, and then moved to Birmingham, where the elder Matthew Boulton made his son a partner at the age of 21. Though the son signed business letters "from father and self", by the mid-1750s he was effectively running the business. The elder Boulton retired in 1757 and died in 1759.  The Boultons had three daughters in the early 1750s, but all died in infancy. Mary Boulton's health deteriorated, and she died in August 1759. Not long after her death Boulton began to woo her sister Anne. Marriage with a deceased wife's sister was forbidden by ecclesiastical law, though permitted by common law. Nonetheless, they married on 25 June 1760 at St. Mary's Church, Rotherhithe. Eric Delieb, who wrote a book on Boulton's silver, with a biographical sketch, suggests that the marriage celebrant, Rev. James Penfold, an impoverished curate, was probably bribed. Boulton later advised another man who was seeking to wed his late wife's sister: "I advise you to say nothing of your intentions but to go quickly and snugly to Scotland or some obscure corner of London, suppose Wapping, and there take lodgings to make yourself a parishioner. When the month is expired and the Law fulfilled, live and be happy ... I recommend silence, secrecy, and Scotland."  The union was opposed by Anne's brother Luke, who feared Boulton would control (and possibly dissipate) much of the Robinson family fortune. In 1764 Luke Robinson died, and his estate passed to his sister Anne and thus into Matthew Boulton's control.  The Boultons had two children, Matthew Robinson Boulton and Anne Boulton. Matthew Robinson in turn had six children with two wives. His eldest son Matthew Piers Watt Boulton, broadly educated and also a man of science, gained some fame posthumously for his invention of the important aeronautical flight control, the aileron. As his father before him, he also had two wives and six children.

Answer: 

Problem: She was born Marem-Ides Leventon (Russian name Adelaida Yakovlevna Leventon) in Yalta, Crimea, Russian Empire. Her stage name Alla Nazimova was a combination of Alla (a diminutive of Adelaida) and the surname of Nadezhda Nazimova, the heroine of the Russian novel Children of the Streets. She was widely known as just Nazimova, and also went under the name Alia Nasimoff. She was the youngest of three children of Jewish parents Yakov Abramovich Leventon, a pharmacist, and Sofia (Sara) Lvovna Horowitz, who moved to Yalta in 1870 from Kishinev.

Nazimova's theater career blossomed early; and by 1903 she was a major star in Moscow and Saint Petersburg. She toured Europe, including London and Berlin, with her boyfriend Pavel Orlenev, a flamboyant actor and producer. In 1905 they moved to New York City and founded a Russian-language theater on the Lower East Side. The venture was unsuccessful; and Orlenev returned to Russia while Nazimova stayed in New York.  She was signed up by the American producer Henry Miller and made her Broadway debut in New York City in 1906 to critical and popular success. Her English-language premiere in November 1906 was in the title role of Hedda Gabler. She quickly became extremely popular (a theater was named after her) and remained a major Broadway star for years, often acting in the plays of Henrik Ibsen and Anton Chekhov. Dorothy Parker described her as the finest Hedda Gabler she had ever seen.  Due to her notoriety in a 35-minute 1915 play entitled War Brides, Nazimova made her silent film debut in 1916 in the filmed version of the play, which was produced by Lewis J. Selznick. A young actor with a bit part in the movie was Richard Barthelmess, whose mother taught Nazimova English. Nazimova had encouraged him to try out for movies and he later became a star. In 1917, she negotiated a contract with Metro Pictures, a precursor to MGM, that included a weekly salary of $13,000. She moved from New York to Hollywood, where she made a number of highly successful films for Metro that earned her considerable money. In 1927, she became a naturalized citizen of the United States.  Nazimova soon felt confident enough in her abilities to begin producing and writing films in which she also starred. In her film adaptations of works by such notable writers as Oscar Wilde and Ibsen, she developed her own filmmaking techniques, which were considered daring at the time. Her projects, including A Doll's House (1922), based on Ibsen, and Salome (1923), based on Wilde's play, were critical and commercial failures.  By 1925 Nazimova could no longer afford to invest in more films; and financial backers withdrew their support. Left with few options, she gave up on the film industry, returning to perform on Broadway, notably starring as Natalya Petrovna in Rouben Mamoulian's 1930 New York production of Turgenev's A Month in the Country and an acclaimed performance as Mrs. Alving in Ibsen's Ghosts, which the critic Pauline Kael later described as the greatest performance she had ever seen on the American stage. In the early 1940s, she appeared in a few more films, playing Robert Taylor's mother in Escape (1940) and Tyrone Power's mother in Blood and Sand (1941). This late return to motion pictures fortunately preserves Nazimova and her art on sound film.
