Sal Khan

• 1. Introduction

  ›

  Sal Khan appeared on the cover of Forbes in 2012 beneath a bold tagline: "The $1 Trillion Opportunity." The phrase did not describe a gadget or a start-up with a flashy product. It described free lessons, recorded by one teacher and open to anyone. Salman Amin Khan is an American educator, and his name has become shorthand for a particular way of learning. Who is the person behind that tagline? What shaped a teacher who grew up counting every dollar? And what does he believe about how people actually learn?

  ›

  Metairie, Louisiana, is where Salman Khan was born on the 11th of October 1976, into a Bengali Muslim family.

  His father, Fakhrul Amin Khan, was a physician who died in 1990. The elder Khan came from the village of Rahmatpur in Babuganj Upazila, Bangladesh. His mother, Masuda Khan, comes from Murshidabad in West Bengal, India.

  The family traces its ancestry to Rahmat Khan, a Pashtun chieftain of the 16th century. He was killed in battle against Kandarpanarayan Rai, the Raja of Chandradwip. In more recent memory, Khan's grandfather Abdul Wahab Khan was a prominent Bengali politician. He served as the third official Speaker of Pakistan's National Assembly.

  In 1993, Khan's mother earned $16,000. He remembers the number because he prepared her taxes himself to obtain financial aid. He describes his upbringing as one marked by financial difficulty. That same year he was still a student at a Louisiana high school, and he would later describe its mix of classmates in vivid terms.

• 3. Schooling and Degrees

  ›

  Grace King High School, in Khan's recollection, held students headed in very different directions: "a few classmates were fresh out of jail and others were bound for top universities."

  He drew cartoons for the school newspaper. While still in high school he also took mathematics courses at the University of New Orleans. He graduated as valedictorian in 1994.

  In 1998 he finished at the Massachusetts Institute of Technology with a double major bachelor's degree. One major was Electrical Engineering and Computer Science, the other was Mathematics. He also earned a Master of Engineering degree in Electrical Engineering and Computer Science. In 2012 he came back to MIT as commencement speaker, the youngest the school had chosen in 30 years.

  Harvard Business School awarded him a Master of Business Administration in 2003. That degree pointed him toward finance, and he would spend years there before teaching took over.

• 4. A Cousin and a Notepad

  ›

  A summer internship at Xerox PARC in 2002 came just before Khan's career in finance. From 2003 until late 2009, he worked as a hedge fund analyst at Connective Capital Management.

  In 2004, Khan began tutoring his cousin Nadia in mathematics over the internet. The tool was the Doodle notepad from Yahoo!. Other relatives and friends soon asked for lessons of their own, so he founded Khan Academy in 2006 and moved his tutorials to YouTube. He created his channel account on the 16th of November 2006.

  In 2009, the popularity of the videos led Khan to quit his analyst job. His close friend Josh Gefner helped as he turned to the channel full-time. In 2010, Shantanu Sinhal, his freshman-year roommate at MIT, was appointed the Academy's president. Khan also received sponsorship from Ann Doerr, the wife of John Doerr.

  By 2009, Khan already planned to widen the free school beyond math and science, with English literature on his list.

• 5. The Teaching Idea

  ›

  One short statement of purpose guides the whole project. Khan wants to "accelerate learning for students of all ages. With this in mind, we want to share our content with whoever may find it useful."

  He argues that classroom technology can free teachers from delivering lectures. That leaves them more time to meet the particular needs of each student.

  His central principle is that students learn better when they control the pace at which they pick up new knowledge. Afterward, they should work together in teams to apply what they learned. This arrangement is called a flipped classroom. It also borrows from the mastery learning of Benjamin Bloom.

  Khan laid out his goals for education in a book, The One World Schoolhouse: Education Reimagined.

  In 2014, he founded Khan Lab School, a private, in-person school in Mountain View, California. It is the place where he puts these ideas to the test.

• 6. Reach and Acclaim

  ›

  By 2023, Khan Academy had more than 155 million registered users. Students had spent billions of hours learning on it.

  As of 2026, the Khan Academy channel on YouTube has 9.31 million subscribers, and its videos have been viewed more than two billion times. Khan has produced over 6,500 video lessons. They began with mathematics and science and now span a wide range of academic subjects.

  The Coach feature arrived in 2012, linking teachers and students through videos and monitoring tools. In 2015, Khan announced a partnership with the College Board to build free practice resources for the SAT.

  Andrew Ng, a Stanford AI researcher, has named Khan as an inspiration for founding Coursera, one of the first massive open online course platforms.

  In 2010, the Bill and Melinda Gates Foundation became one of the academy's biggest supporters. Bill Gates has said: "I've used Khan Academy with my kids, and I'm amazed at the breadth of Sal's subject expertise and his ability to make complicated topics understandable."

  Time magazine named Khan to its Time 100 list of influential people in 2012.

• 7. Beyond YouTube

  ›

  Early in 2020, as the COVID-19 pandemic spread, Khan launched Schoolhouse. It is a free non-profit initiative that arranges small-group tutoring for students around the world over Zoom.

  Schoolhouse also offers certifications, developed with the University of Chicago, that test whether students have mastered a subject. MIT, Caltech, and Case Western Reserve University have since signed on.

  In October 2025, TED announced that Khan would become its new Vision Steward. His role involves advising on TED's long-term direction in education and technology. He succeeds Chris Anderson in the post.

  The American Academy of Achievement gave Khan its Golden Plate Award for public service in 2012. Two years later, he received the 19th Annual Heinz Award in the Human Condition category.

  In 2016, the President of India presented him with the Padma Shri, the fourth-highest civilian award of the Republic of India.

  On the 27th of May 2021, Harvard University awarded him an honorary Doctor of Laws degree. On the 11th of May 2025, Carnegie Mellon University conferred an honorary Doctor of Humane Letters.

  Khan is married to Umaima Marvi, a physician, and the couple live with their children in Mountain View, California. Their first child, a son, had epilepsy in childhood and later outgrew it. The experience left the family with a lasting sense of what matters most in life.

  Khan has also described his beliefs. He says that if you try to make the best of the finite years we have, "while not making it any worse for anyone else," and are "humbled by the vastness and mystery of the Universe, then I'm the same religion as you."

  During his childhood, Khan played the guitar.
