Edward George Geoffrey Smith-Stanley, [[KnightFever 14th Earl of Derby KG PC]], known before 1834 as Edward Stanley, and from 1834 to 1851 as Lord Stanley, had a really weird career. The longest ever serving leader of the Conservative Party he was Prime Minister three times (something only three other Prime Ministers ever matched), but his total time as Prime Minister was just over 4 years and none of his stints were longer than 2 years, making him one of the most frequent [=PMs=] '''and''' a fairly short term incumbent.
The first ministry was literally a few months and is known as ''The "Who? Who?" Ministry''. Lord Derby was the Prime Minister and Creator/BenjaminDisraeli served as Chancellor of the Exchequer. It was also first time the Protectionist wing of the party had taken office since the Corn Laws schism of 1846. Ultimately however it was doomed. There were almost no established names in the cabinet. So much so that the aging [[TheDukeOfWellington Duke of Wellington]] kept interrupting the announcing of the ministers in the House of Lords by saying "Who? Who?" at the top of his voice. (Derby was well aware of this, and turned down Victoria asking him to form a government several times until the situation forced it; thus he was perhaps the first Prime Minister of the United Kingdom ''[[TopGear who didn't want to be one]]'').
In 1858, Derby formed another minority government when TheViscountPalmerston's first ministry collapsed. This was the government that brought India directly under British Rule rather than that of the East India Company. Then it fell apart.
In 1866 he was back after Creator/EarlRussell's second government fell apart. Yet again Disraeli was a big player. In fact historians tend to consider that the Derby governments were dominated by Disraeli. This was the government that passed the Second Reform act. In 1868 Derby retired and [[Creator/BenjaminDisraeli guess who]] took up the reigns.
Regarded by many as The Father of The Conservative Party.
His second son, Frederick Arthur Stanley, 16th Earl of Derby, KG GB GCVO PC, was named Governor General of Canada in 1888 and is well known in that country as the namesake of the StanleyCup.
