Career Graham was partner to the influential English clockmaker Thomas Tompion during the last few years of Tompion's life.

He was made Master of the Worshipful Company of Clockmakers in 1722. Between 1730 and 1738, Graham had as an apprentice Thomas Mudge, who went on to be an eminent watchmaker in his own right, and invented the lever escapement, an important development for pocket watches.Harold Bagust, "The Greater Genius?", 2006, Ian Allan Publishing, (page 15) He was widely ...

The related () was used in Portugal, Brazil, and other parts of the Portuguese Empire until the adoption of the metric system. Definition Unit of length * 1 toise was divided in 6 feet (french: pieds) or 72 inches () or 864 lines () in France until 1812. : In 1799 the metre was defined to be exactly 443.296 or toise, with the intention that the metre should equal of the distance from the pole to the equator. This had the effect of making the toise approximately 1949.03631 mm. : According to an article written in 1866, during measurement of various standard length artefacts from several countries, the toise was measured as 1,949.03632 mm. :Since before 1394, the standard for the toise of Paris was an iron ...

She was the sovereign of Austria, Hungary, Croatia, Bohemia, Transylvania, Mantua, Milan, Lodomeria and Galicia, the Austrian Netherlands, and Parma. By marriage, she was Duchess of Lorraine, Grand Duchess of Tuscany and Holy Roman Empress. Maria Theresa started her 40-year reign when her father, Emperor Charles VI, died on 20 October 1740. Charles VI paved the way for her accession with the Pragmatic Sanction of 1713 and spent his entire reign securing it. He neglected the advice of Prince Eugene of Savoy, who believed that a strong military and a rich treasury were more important than mere signatures. Eventually, Charles VI left behind a weakened and impoverished state, particularly due to the War of the Polish Succession and the Rus ...

Lodomeria
Lodomeria is the Latinized name of Volodymyr (Old Slavic: , ; uk, Лодомерія, ; pl, Lodomeria; sk, Lodomeria; hu, Lodomeria; cz, Vladiměř; ; ro, Lodomeria), a Ruthenian principality also referred to as the Principality of Volhynia, which was founded by the Rurik dynasty in 987 in the western parts of Kievan Rus'. It was centered on the region of Volhynia, straddling the borders of modern-day Poland, Ukraine and Belarus. The Principality of Volodymyr arose in the course of the 12th century along with the Principality of Halych. "Vladimir" is the Russian form of the name of the city now called Volodymyr, which was the capital of the Principality. Upon the first partition of Poland in 1772, the name "Kingdom of Galicia and Lodomeria" (probably in reference to the Kingdom of Galicia–Volhynia) was granted to the Polish territories which passed to the Habsburg monarchy, while most of Volhynia (including the city of Vladimir) remained as part of rump Poland until eve ...
