We would like to introduce you to David Lowenherz, Auctionata expert in Autographs.

David Lowenherz was first introduced to the world of autograph collecting through his father. In 1978, aged 27, he opened Lion Heart Autographs in New York, with international ambition. Focusing on American and European material, the business became one of the premier historical manuscript dealers in the US. It specialises in art, history, literature, music, and science.

For over three decades, David has helped hundreds of satisfied customers build their collections; some even refer to him as their “personal curator.” A member of the Grolier Club, he owns one of the finest private Robert Frost collections.

He has completed complex estate appraisals for Carnegie Hall, The New York Times and many famous individuals, including Irving Berlin, Leonard Bernstein and Martha Graham. Items he has handled include an eight-song manuscript by Schubert; letters by Beethoven; manuscripts by Einstein; items written by every US president; a proclamation signed by Napoleon; a letter from Martin Luther King, Jr., referring to his “I Have a Dream” speech; one of only six known letters from Sigmund Freud to his mother; and a significant archive of Alfred Dreyfus material.

In 2000, David began a series of books on famous and important letters organised by theme. The first, The 50 Greatest Love Letters of All Time, received enormous attention and praise since its 2002 release; and was also published in Israel, Italy, China, Japan and Korea. It was followed by The 50 Greatest Letters from America’s Wars.

David Lowenherz lives and works in New York.

Wagner's script

Some decades ago, a New York auction house whose name begins with the letter "S" mailed out its latest catalogue of autographs and manuscripts. I took the catalogue home with me one evening, sat down in my armchair and began to work my way through it without a great deal of interest, until I got to the letter "W." At that point I read a very unusual and intriguing entry.
