Tendulkar was born on 24 April 1973 into a Rajapur Saraswat Brahmin family in Mumbai. His father Ramesh Tendulkar was a reputed Marathi novelist and his mother Rajni worked in the insurance industry.Ramesh named Tendulkar after his favourite music director, Sachin Dev Burman. Tendulkar has three elder siblings: two half-brothers Nitin and Ajit, and a half-sister Savita. They were Ramesh’s children from his first marriage. He spent his formative years in the Sahitya Sahawas Cooperative Housing Society, Bandra (East), Mumbai. As a young boy, Tendulkar was considered a bully, and often picked up fights with new children in his school. He also showed an interest in tennis, idolising John McEnroe. To help curb his mischievous and bullying tendencies, Ajit introduced him to cricket in 1984. He introduced the young Sachin to Ramakant Achrekar, a famous cricket coach of Mumbai and a club cricketer of repute, at Shivaji Park, Dadar, Mumbai.
Achrekar was impressed with Tendulkar’s talent and advised him to shift his schooling to Sharadashram Vidyamandir (English) High School, a school at Dadar which had a dominant cricket team and had produced many notable cricketers. Prior to this, Tendulkar had attended the Indian Education Society’s New English School in Bandra (East).He was also coached under the guidance of Achrekar at Shivaji Park in the mornings and evenings. Tendulkar would practice for hours on end in the nets. If he became exhausted, Achrekar would put a one-rupee coin on the top of the stumps, and the bowler who dismissed Tendulkar would get the coin. If Tendulkar passed the whole session without getting dismissed, the coach would give him the coin. Tendulkar now considers the 13 coins he won then as some of his most prized possessions. He moved in with his aunt and uncle, who lived near Shivaji Park, during this period, due to his hectic schedule.
Meanwhile at school, he developed a reputation as a child prodigy. He had become a common conversation point in Mumbai cricketing circles, where there were suggestions already that he would become one of the greats. Besides school cricket, he also played club cricket, initially representing John Bright Cricket Club inMumbai’s premier club cricket tournament, the Kanga League, and later went on to play for the Cricket Club of India. In 1987, at the age of 14, he attended the MRF Pace Foundation in Madras (now Chennai) to train as a fast bowler, but Australian fast bowler Dennis Lillee, who took a world record 355 Test wickets, was unimpressed, suggesting that Tendulkar focus on his batting instead. A couple of months later, former Indian batsman Sunil Gavaskar gave him a pair of his own ultra light pads. “It was the greatest source of encouragement for me,” Tendulkar said nearly 20 years later after surpassing Gavaskar’s world record of 34 Test centuries. His season in 1988 was extraordinary, with Tendulkar scoring a century in every innings he played. He was involved in an unbroken 664-run partnership in a Lord Harris Shield inter-school game against Anjuman-E-Islam High School in 1988 with his friend and team-mate Vinod Kambli, who would also go on to represent India. The destructive pair reduced one bowler to tears and made the rest of the opposition unwilling to continue the game. Tendulkar scored 326 (not out) in this innings and scored over a thousand runs in the tournament. This was a record partnership in any form of cricket until 2006, when it was broken by two under-13 batsmen in a match held at Hyderabad in India.
On 24 May 1995, at the age of 22, Tendulkar married Anjali, a paediatrician and daughter of Gujarati industrialist Anand Mehta and British social worker Annabel Mehta. Anjali is six years his senior. They have two children, Sara (born 12 October 1997) and Arjun (born 24 September 1999). Arjun, a left handed batsman, has recently been included in under-14 probables list of Mumbai Cricket Association for off-season training camp. In January 2013 he was selected in Mumbai under-14 team for the west zone league
