How Eliza Hamilton’s copy of “The Federalist” wound up in Thomas Jefferson’s library

Posted by: Neely Tucker

The Library has two fascinating copies of “The Federalist,” the influential collection of newspaper essays that urged the ratification of the U.S. Constitution. These copies have deep personal ties to three Founding Fathers. One was owned by Elizabeth Hamilton, the wife of Alexander Hamilton (who wrote most of the 85 essays that composed the volume). She gave her copy to her sister, Angelica, who in turn gave it to Thomas Jefferson, her friend. Jefferson put it in his personal library, which became the foundation of the Library of Congress. The other copy belonged to James Madison, who wrote more than two dozen "Federalist" essays, and, like Jefferson, served as President of the new nation.

Last Men of the (American) Revolution

Posted by: Mark Hartsell

In 1864, while America was in the depths of the Civil War, photographers Nelson and Roswell Moore set out to photograph what they believed were the last surviving men who had fought in the American Revolution. The men were all over 100 years old. The photographs spawned a popular book, "The Last Men of the Revolution," and the Library today preserves the photographs of those last survivors.

The Moon map that made history

The moon always has been an object of fascination for mankind, but once President John F. Kennedy pledged in 1961 that the U.S. would send a manned spacecraft there within a decade, one of the first questions was entirely practical: Where would they land? An extraordinary map, the USAF Lunar Wall Mosaic, produced the year after Kennedy's speech, helped provide the answer. The 1969 Apollo 11 mission landed safely in an area called the Mare Tranquillitatis (Sea of Tranquility). Today, a copy of the map is preserved at the Library as one of the most important -- and practical -- maps in human history.

Hampton Sides, the bestselling author of several books about daring expeditions, including “In the Kingdom of Ice” and “The Wide Wide Sea,” writes this guest essay, in which he argues that to explore is to be human. It's the concluding article in the March-April issue of the Library of Congress Magazine, "Into the Unknown," about world-changing voyages and discoveries chronicled in the Library's collections.

Lost on the ice: The 1897 hydrogen balloon attempt to reach the North Pole

Posted by: Neely Tucker

Only traces remain of Salomon August Andrée’s 1897 attempt to reach the North Pole. From a base on the Svalbard archipelago, the engineer and his two companions had hoped to float a hydrogen balloon gracefully over the pole, drop a Swedish flag and claim the glory of first discovery. Their friends never saw them alive again. Their remains were found in 1930 on a small island in the Arctic Ocean and the story became internationally famous. The Library preserves several artifacts from the expedition, including fabric samples from the construction of the balloon.

Marie Tharp, the scientist who mapped the ocean floor

Posted by: Neely Tucker

Marie Tharp was an American geologist and marine cartographer whose groundbreaking studies into ocean floors and discovery of the mid-Atlantic rift valley challenged the widely accepted geological views of the time. Her papers are preserved at the Library, a window into the thinking of a scientist who changed the understand of the world we live in.
