1945: The United Nations charter was signed in San Francisco by 50 nations.

1870: The first section of the Atlantic City Boardwalk opened along the New Jersey beach. Dr. Jonathan Pitney and civil engineer Richard Osborne began developing the area on Absecon Island in the early 1850s. Long before this time, members of the Lenni-Lenape tribe were the first seasonal visitors to enjoy the summer splendor of the island. Beautiful beaches, fresh sea air, luxurious hotels, fine restaurants, alluring shops, and a connecting railroad line from Camden, New Jersey, drew visitors from all over the world. Atlantic City soon became a popular summer resort and winter health spa. Alexander Boardman, a railroad conductor, and Jacob Keim, a hotelier, conceived of the idea of constructing a boardwalk as a means of keeping sand out of the railroad cars and hotels. The city used its tax revenues to build an eight-foot-wide temporary wooden walkway from the beach into town that could be dismantled during the winter. (Source: Library of Congress)
