The Speed of Dark reveals how the author, his mother the daughter of the French Rothschild banking dynasty and his father a world-renowned cellist, broke the chain of his lineage of art, music and banking to establish an important career in science. Born in the rural Adirondacks as an American citizen after his European parents and sister narrowly escaped Nazi Germany, he spoke French before English, was raised with financial security, was exposed to Rothschild palaces visiting his French grandparents, felt as a foreigner with his Russian family in Moscow, and often felt French in his native America. As a child, he felt simultaneously as his father's son, yet a guest in the audience when listening to the pinnacle of music played in his home by the greatest artists. As a developing scientist, he benefited by his charismatic father's influence who asked such an original, imaginative question, "What about the speed of dark?" Unlike other memoirs about rising from adversity to success, the author brings the reader into the privilege of having a unique family in which the extraordinary is ordinary, and the challenge of being asked, "Are you a failure like the sons of all great men?" The Speed of Dark will resonate with musicians, those interested in art, music and history, and those who seek to carve their own path in a world filled with high expectations and seemingly unlimited resources."

(Hamid Shams, BBP Films Producer and Cinematographer) "This memoir is not just worth reading, it is worth remembering!" (James Mathews, Author of Last Known Position) "This fascinating account of his journey becomes a meditation on art, wonder, and creativity, of bucking the status quo and following one's heart.
