Sahib Singh  Sahib Singh (Gurmukhi: ਸਾਹਿਬ ਸਿੰਘ) (16 February 1892 – 29 October 1977) was a Sikh academic who made a contribution to Sikh literature. He was a grammarian, author, scholar and theologian. He was born in a Hindu family to father Hiranand and was named Natthu Ram. As a youth, Natthu Ram was apprenticed to a Muslim teacher, Hayat Shah, son of Punjabi poet Hashim, to teach him the Persian language. Whilst at junior school, he saw Sikh soldiers and was so impressed with them that he decided to keep unshorn hair. In 1906, when he was in the ninth grade he became Amritdhari and gave himself the name of "Sahib Singh". At that time he stopped learning Persian and started learning Sanskrit, which later on helped him in understanding Guru Granth Sahib. After passing the tenth grade, Sahib Singh joined a local school. Later he applied for a job with the postal department, and got the job, borrowing 20 Rs from his house maid as traveling expenses. Later he left home to pursue higher education. He had nowhere to go, having very little money. He later met Pundit Vesta Parsad, a scholarly teacher for help. Sahib Singh passed his FA and BA and started work at Frakka college and later joined Gujranwala Khalsa college. It was at this college that he met Bava Harkrishan Singh and Bhai Jodh Singh. Sahib Singh's financial situation had improved by this time so that he was able to pay back his debts. The death of his father made the situation hard for him. He entered Dyal Singh College, Lahore, and then the Government College, Lahore where he obtained his bachelor's degree. In 1917 he joined Nanak Khalsa College, Gujranwala as a lecturer in Sanskrit. In 1921 Sahib Singh became the Assistant General Secretary of the SGPC. Sahib Singh took part in Ka Bagh Morcha in 1922 and was arrested. In 1923 he was again arrested when he took part in Jaito Morcha. In 1927 he rejoined Gujranwala college, where he stayed until 1936. At this time he moved to Amritsar and joined the Khalsa college as a lecturer in Punjabi. At the college he met fellow Sikh scholars like Teja Singh, Ganda Singh, Veeram Singh and Mohan Singh.
