Synopses & Reviews
"Dermans memoir of his transition from mathematical physicist to expert finance whiz at Goldman Sachs and Salomon Brothers reads like a novel, but tells a lot about brains applied to making money grow."
Paul A. Samuelson, MIT, Nobel Laureate in Economic Sciences, 1970
"Not only a delightful memoir, but one full of information, both about people and their enterprise. I never thought that I would be interested in quantitative financial analysis, but reading this book has been a fascinating education."
Jeremy Bernstein, author of Oppenheimer: Portrait of an Enigma
"This wonderful autobiography takes place in that special time when scientists discovered Wall Street and Wall Street discovered them. It is elegantly written by a gifted observer who was a pioneering member of the new profession of financial engineering, with an evident affection both for finance as a science and for the scientists who practice it. Dermans portrait of how the academics brought their new financial science to the world of business and forever changed it and, especially, his descriptions of the late and extraordinary genius Fischer Black who became his mentor, reveal a surprising humanity where it might be least expected. Who should read this book? Anyone with a serious interest in finance and everyone who simply wants to enjoy a good read."
Stephen Ross, Franco Modigliani Professor of Finance and Economics, Sloan School, MIT
a deep and elegant exploration by a thinker who moved from the hardest of all sciences (physics) to the softest of the soft (finance). Derman is a different class of thinker; unlike most financial economists, he bears no physics envy and focuses on exploring the real intuitions behind the mechanisms themselves. In addition to stories and portraits, the book documents, in vivid detail, the methods of knowledge transfer. I know of no other book that bridges the two cultures. Finally, I am happy to discover that Derman has a third career: he is a writer."
Nassim Taleb, author of Fooled by Randomness
"The quintessential quarky quant, Emanuel Derman has it all. Physicist, mathematician, philosopher, and poet blend together to produce a narrative that all financial engineers will find worth reading."
Mark Rubinstein, Paul Stephens Professor of Applied Investment Analysis, University of California, Berkeley
"My Life as a Quant...is, indeed, a perfect memoir, as Derman, a South African-born physicist turned financial engineer, is a perfect memoirist." Grant's Interest Rate Observer

Emanuel Derman was one of the first physicists to move to Wall Street, and his career paralleled the growth of quantitative trading over the past twenty years. In My Life as a Quant
, he traces his transformation from ambitious young scientist to managing director and head of the renowned Quantitative Strategies group at Goldman, Sachs & Co.
Derman's tale recounts his adventures with quants, traders and other high fliers on Wall Street as he became the best-known quant in the business. He describes the struggles of research and his interactions with an assorted cast of famous scientists. He relates his impressions of some of the most creative minds on Wall Street, including Fischer Black, with whom he collaborated on the widely used Black-Derman-Toy model of interest rates. Throughout his story he reflects on the appropriate way to apply the refined methods of physics to the hurly-burly world of markets and the people that inhabit them.
As investment firms increasingly rely on advanced quantitative financial models to generate profits, large "quant" departments staffed by former physicists, mathematicians, and computer scientists have become routine on Wall Street. Emanuel Derman, one of the first physicists to move to Wall Street, is its most well-known quant whose career path parallels the growth of quantitative modeling. My Life as a Quant traces his pilgrim's progress from ambitious academic scientist to managing director and head of the renowned Quantitative Strategies group at Goldman, Sachs & Co., one of the world's most elite investment firms. Derman reveals his experiences learning to adapt the methods of science to finance and working with some of the finest minds in the business, including Fischer Black (with whom he developed the widely used Black-Derman-Toy model of interest rates). He also recounts his adventures with other quants, traders, and other high fliers on Wall Street.
Wall Street is no longer the old-fashioned business it once was. In recent years, investment banks and hedge funds have increasingly turned to quantitative trading strategies and derivative securities for their profits, and have raided academia for PhDs to model these volatile products and manage their risk. Nowadays, the fortunes of firms and the stability of markets often rest on mathematical models. "Quants"the scientifically trained practitioners of quantitative finance who build these modelshave become key players on the Wall Street stage.
And no Wall Street quant is better known than Emanuel Derman. One of the first high-energy particle physicists to migrate to Wall Street, he spent seventeen years in the business, eventually becoming managing director and head of the renowned Quantitative Strategies group at Goldman, Sachs & Co. There he coauthored some of todays most widely used and influential financial models.
Physics and quantitative finance look deceptively similar. But, writes Derman, "When you do physics youre playing against God; in finance, youre playing against Gods creatures." How can one justify using the precise methods of physics in the frenzied world of financial markets? Is it reasonable to treat the economy and its markets as a complex machine? Or is quantitative finance merely flawed thinking masquerading as science, a brave whistling in the dark?
My Life as a Quant is Dermans entertaining and candid account of his search for answers as he undergoes his transformation from ambitious young scientist to managing director. His book is simultaneously wide-ranging and personal. He tells the story of his passage between two worlds; he recounts his adventures with physicists, quants, options traders, and other highfliers on Wall Street; he analyzes the incompatible personas of traders and quants; and he meditates on the dissimilar natures of knowledge in physics and finance. Throughout his tale, he reflects on the appropriate way to apply the refined methods of physics to the hurly-burly world of markets.
My Life as a Quant is a unique first-person story and a perceptive and revealing exploration of the quantitative side of Wall Street.
In My Life as a Quant, Emanuel Derman relives his exciting journey as one of the first high-energy particle physicists to migrate to Wall Street. Page by page, Derman details his adventures in this field—analyzing the incompatible personas of traders and quants, and discussing the dissimilar nature of knowledge in physics and finance. Throughout this tale, he also reflects on the appropriate way to apply the refined methods of physics to the hurly-burly world of markets.
