The (Newly Revealed) Wonders of a 16th Century Portolan Chart of the North American Coast

Posted by: Wendi Maloney

New details about early European explorations along the North American east coast have been gleaned from a 16th-century portolan chart by the Library's Preservation and Research Testing Division. Using multispectral imaging and other techniques, Library staff has discovered multiple place names on the chart that could not be seen by the naked eye.

Einstein’s Love Affair at Princeton

Posted by: Neely Tucker

The Library has six letters that Albert Einstein wrote to Margarita Konenkova, a Russian national with whom he had a passionate, late-in-life affair while he was at Princeton. Einstein was a widower, Konekova was married to a famous Russian sculptor. The affair was not revealed until 1994. The letters, our staff experts write, mix Einstein’s humanity with his genius.

Carl Sagan: Childhood Dreams of Space Flight

Posted by: Neely Tucker

Carl Sagan's dreams of space flight took root as a child as some of his enthusiastic artwork shows, particularly a drawing he called “The Evolution of Interstellar Flight.” It's in the Library's Seth MacFarlane Collection of the Carl Sagan and Ann Druyan Archive, composed of more than 595,000 items from throughout the astrophysicist's life.

Oppenheimer: The Library’s Collection Chronicles His Life

Posted by: Neely Tucker

The stunningly complete, intellectually voracious files of J. Robert Oppenheimer, father of the atomic bomb, are preserved at the Library. The files fill more than 300 boxes that occupy a line of files that would stretch, if stacked end to end, more than 120 feet. That’s not including more than 70 boxes of research files compiled over 20 years by Martin J. Sherwin for his part of the Pulitzer Prize-winning biography, “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer.” (Kai Bird shared the Pulitzer as a co-writer.) Those stretch another 27 feet. The files tell his epic life story in granular detail.

Fabulous Flutes

Posted by: Mark Hartsell

Lizzo set the social media world afire last fall by playing, in concert, a short solo on a rare crystal flute that once belonged to President James Madison. The flute is one of the Library's most prized musical instruments and a showpiece of the collection of Dayton C. Miller, the famed physicist, astronomer and major flute aficionado. The collection, preserved in a vault at the Library, is not just the world’s largest of flute-related material, it is perhaps the largest collection on a single music subject ever assembled — and it’s what drew Lizzo to the Library in the first place.
