Raymond Kurzweil (/ˈkɜːrzwaɪl/ KURZ-wyle; born February 12, 1948) is an American inventor and futurist. He is involved in fields such as optical character recognition (OCR), text-to-speech synthesis, speech recognition technology, and electronic keyboard instruments. He has written books on health, artificial intelligence (AI), transhumanism, the technological singularity, and futurism. Kurzweil is a public advocate for the futurist and transhumanist movements, and gives public talks to share his optimistic outlook on life extension technologies and the future of nanotechnology, robotics, and biotechnology.

Kurzweil received the 1999 National Medal of Technology and Innovation, the United States' highest honor in technology, from President Clinton in a White House ceremony. He was the recipient of the $500,000 Lemelson-MIT Prize for 2001. And in 2002 he was inducted into the National Inventors Hall of Fame, established by the U.S. Patent Office. He has received 21 honorary doctorates, and honors from three U.S. presidents. The Public Broadcasting Service (PBS) included Kurzweil as one of 16 "revolutionaries who made America" along with other inventors of the past two centuries. Inc. magazine ranked him #8 among the "most fascinating" entrepreneurs in the United States and called him "Edison's rightful heir".

Kurzweil has written seven books, five of which have been national bestsellers.The Age of Spiritual Machines has been translated into 9 languages and was the #1 best-selling book on Amazon in science. Kurzweil's book The Singularity Is Near was a New York Times bestseller, and has been the #1 book on Amazon in both science and philosophy. Kurzweil speaks widely to audiences both public and private and regularly delivers keynote speeches at industry conferences like DEMO, SXSW, and TED. He maintains the news website KurzweilAI.net, which has over three million readers annually.

Kurzweil has been employed by Google since 2012, where he is a "director of engineering".


Ray Kurzweil grew up in the New York City borough of Queens. He attended NYC Public Education Kingsbury Elementary School PS188. He was born to secular Jewish parents who had emigrated from Austria just before the onset of World War II. He was exposed via Unitarian Universalism to a diversity of religious faiths during his upbringing. His Unitarian church had the philosophy of many paths to the truth – the religious education consisted of studying a single religion for six months before moving on to the next. His father, Fredric was a concert pianist, a noted conductor, and a music educator. His mother, Hannah was a visual artist. He has one sibling, his sister Enid.

Kurzweil decided he wanted to be an inventor at the age of five. As a young boy, Kurzweil had an inventory of parts from various construction toys he'd been given and old electronic gadgets he'd collected from neighbors. In his youth, Kurzweil was an avid reader of science fiction literature. At the age of eight, nine, and ten, he read the entire Tom Swift Jr. series. At the age of seven or eight, he built a robotic puppet theater and robotic game. He was involved with computers by the age of 12 (in 1960), when only a dozen computers existed in all of New York City, and built computing devices and statistical programs for the predecessor of Head Start. At the age of fourteen, Kurzweil wrote a paper detailing his theory of the neocortex. His parents were involved with the arts, and he is quoted in the documentary Transcendent Man as saying that the household always produced discussions about the future and technology.

Kurzweil attended Martin Van Buren High School. During class, he often held onto his class textbooks to seemingly participate, but instead, focused on his own projects which were hidden behind the book. His uncle, an engineer at Bell Labs, taught young Kurzweil the basics of computer science. In 1963, at age 15, he wrote his first computer program. He created pattern-recognition software that analyzed the works of classical composers, and then synthesized its own songs in similar styles. In 1965, he was invited to appear on the CBS television program I've Got a Secret, where he performed a piano piece that was composed by a computer he also had built. Later that year, he won first prize in the International Science Fair for the invention; Kurzweil's submission to Westinghouse Talent Search of his first computer program alongside several other projects resulted in him being one of its national winners, which allowed him to be personally congratulated by President Lyndon B. Johnson during a White House ceremony. These activities collectively impressed upon Kurzweil the belief that nearly any problem could be overcome.

While in high school, Kurzweil had corresponded with Marvin Minsky and was invited to visit him at MIT, which he did. Kurzweil also visited Frank Rosenblatt at Cornell.

He obtained a B.S. in computer science and literature in 1970 at MIT. He went to MIT to study with Marvin Minsky. He took all of the computer programming courses (eight or nine) offered at MIT in the first year and a half.

In 1968, during his sophomore year at MIT, Kurzweil started a company that used a computer program to match high school students with colleges. The program, called the Select College Consulting Program, was designed by him and compared thousands of different criteria about each college with questionnaire answers submitted by each student applicant. Around this time, he sold the company to Harcourt, Brace and World for $100,000 (roughly $670,000 in 2013 dollars) plus royalties.

In 1974, Kurzweil founded Kurzweil Computer Products, Inc. and led development of the first omni-font optical character recognition system, a computer program capable of recognizing text written in any normal font. Before that time, scanners had only been able to read text written in a few fonts. He decided that the best application of this technology would be to create a reading machine, which would allow blind people to understand written text by having a computer read it to them aloud. However, this device required the invention of two enabling technologies—the CCD flatbed scanner and the text-to-speech synthesizer. Development of these technologies was completed at other institutions such as Bell Labs, and on January 13, 1976, the finished product was unveiled during a news conference headed by him and the leaders of the National Federation of the Blind. Called the Kurzweil Reading Machine, the device covered an entire tabletop.

Kurzweil's next major business venture began in 1978, when Kurzweil Computer Products began selling a commercial version of the optical character recognition computer program. LexisNexis was one of the first customers, and bought the program to upload paper legal and news documents onto its nascent online databases.

Kurzweil sold his Kurzweil Computer Products to Lernout and Hauspie. Following the legal and bankruptcy problems of the latter, the system became a subsidiary of Xerox later known as Scansoft and now as Nuance Communications, and he functioned as a consultant for the former until 1995.

Kurzweil's next business venture was in the realm of electronic music technology. After a 1982 meeting with Stevie Wonder, in which the latter lamented the divide in capabilities and qualities between electronic synthesizers and traditional musical instruments, Kurzweil was inspired to create a new generation of music synthesizers capable of accurately duplicating the sounds of real instruments. Kurzweil Music Systems was founded in the same year, and in 1984, the Kurzweil K250 was unveiled. The machine was capable of imitating a number of instruments, and in tests musicians were unable to discern the difference between the Kurzweil K250 on piano mode from a normal grand piano. The recording and mixing abilities of the machine, coupled with its abilities to imitate different instruments, made it possible for a single user to compose and play an entire orchestral piece.

Kurzweil Music Systems was sold to South Korean musical instrument manufacturer Young Chang in 1990. As with Xerox, Kurzweil remained as a consultant for several years. Hyundai acquired Young Chang in 2006 and in January 2007 appointed Raymond Kurzweil as Chief Strategy Officer of Kurzweil Music Systems.

Concurrent with Kurzweil Music Systems, Kurzweil created the company Kurzweil Applied Intelligence (KAI) to develop computer speech recognition systems for commercial use. The first product, which debuted in 1987, was an early speech recognition program.

Kurzweil started Kurzweil Educational Systems in 1996 to develop new pattern-recognition-based computer technologies to help people with disabilities such as blindness, dyslexia and attention-deficit hyperactivity disorder (ADHD) in school. Products include the Kurzweil 1000 text-to-speech converter software program, which enables a computer to read electronic and scanned text aloud to blind or visually impaired users, and the Kurzweil 3000 program, which is a multifaceted electronic learning system that helps with reading, writing, and study skills.

During the 1990s, Kurzweil founded the Medical Learning Company. The company's products included an interactive computer education program for doctors and a computer-simulated patient. Around the same time, Kurzweil started KurzweilCyberArt.com—a website featuring computer programs to assist the creative art process. The site used to offer free downloads of a program called AARON—a visual art synthesizer developed by Harold Cohen—and of "Kurzweil's Cybernetic Poet", which automatically creates poetry. During this period he also started KurzweilAI.net, a website devoted towards showcasing news of scientific developments, publicizing the ideas of high-tech thinkers and critics alike, and promoting futurist-related discussion among the general population through the Mind-X forum.

In 1999, Kurzweil created a hedge fund called "FatKat" (Financial Accelerating Transactions from Kurzweil Adaptive Technologies), which began trading in 2006. He has stated that the ultimate aim is to improve the performance of FatKat's A.I. investment software program, enhancing its ability to recognize patterns in "currency fluctuations and stock-ownership trends." He predicted in his 1999 book, The Age of Spiritual Machines, that computers will one day prove superior to the best human financial minds at making profitable investment decisions.In June 2005, Kurzweil introduced the "Kurzweil-National Federation of the Blind Reader" (K-NFB Reader)—a pocket-sized device consisting of a digital camera and computer unit. Like the Kurzweil Reading Machine of almost 30 years before, the K-NFB Reader is designed to aid blind people by reading written text aloud. The newer machine is portable and scans text through digital camera images, while the older machine is large and scans text through flatbed scanning.

In December 2012, Kurzweil was hired by Google in a full-time position to "work on new projects involving machine learning and language processing". He was personally hired by Google co-founder Larry Page. Larry Page and Kurzweil agreed on a one-sentence job description: "to bring natural language understanding to Google".
