Balamurali Ambati was born on July 29, 1977. His mother was a Tamil linguist and a mathematician, his father was a doctor. When Balamurali was three, his family immigrated to Buffalo, New York, from Vellore, India, for better life. Balamurali was an extraordinary child ever since he was born. At the age of four, Ambati was doing calculus and did maths puzzles. At the age of six, he started elementary school and in some weeks of his joining the first grade, Balamurali was put into the second grade. Balamurali’s father motivated his young son to try studying things two times faster because his son was smarter than other children of his age. He achieved two elementary school grades each year and completed his studies in high school in Baltimore at the age of 11. That year, he also wrote a book on medicine with his 17-year-old brother, Jayakrishna, which won an award from the American Medical Association. Some activities that interested Balamurali when he was growing up included basketball, chess, ping-pong and video games. At secondary school, he was keen on biology, which later helped him to choose a profession in medicine. By the time he was 13 years old, he had completed his studies at New York University and went on to study at Mount Sinai School of Medicine, which he successfully completed and was awarded with a doctor diploma at the young age of 17. In 1995, according to the Guinness Book of World Records he was the world’s youngest doctor, at the age of seventeen. Balamurali said that by the age of 7 he had decided on his future profession. “I spilled a pot of very hot water onto myself. I was in the hospital for a few months. I understood then I wanted to do something where I could help sick people.” Presently, Dr Ambati is known as a brilliant ophthalmologist who has made significant contributions to medical science. He is a person who loves to explore and comes up with new forms of treatments for abnormal levels of diseases. Dr Ambati has got a lot of awards for his medical brilliance. He has also volunteered to work with Orbis International, a charity organisation, which offers medical help to many developing countries around the world. 1. Balamurali was born in India. (T/F/NS) 2.
