William Lamb, 2nd Viscount Melbourne,, in some sources called Henry William Lamb, was a British home secretary (1830–1834) and prime minister. He is best known for being prime minister in Queen Victoria's early years and coaching her in the ways of politics, acting almost as her private secretary. Historians have concluded that Melbourne does not rank highly as a Prime Minister, for there were no great foreign wars or domestic issues to handle, he lacked major achievements, he enunciated no grand principles, and he was involved in several political scandals in the early years of Victoria's reign.
