Hans Sloane was president of the RSL, a physician, and a collector of specimens from around the world. He first began by collecting botanical samples from both the Old and New world then expanding to shells,insects, fossils, minerals, etc. He collected samples for their rarity, not for their cohesiveness in relating to each other. He made a profit importing milk chocolate from south Africa and over the years his collection grew to be expansive and all the important minds of the time visited him to view his collection, Carl Linnaeus, Benjamin Franklin, and George Handel to name a few. At his death he established a trust which along with his collection formed the British Museum, the largest museum of the eighteenth century.
