Missed this one............

On the 18th of January in the year 1778 Captain James Cook, one of the greatest explorer of the 18th Century made landfall on the island of Kauai in the Hawaiian Islands. As Cook was the first European to land on these islands he named them the Sandwich Islands after one of his patrons, The Earl of Sandwich. Of course, the good earl was famous for a item that was named after him other than the islands, but that is a story for another day.
