NIRANJAN SINGH, PROFESSOR (1892-1979), educationist and writer, was born in 1892, the youngest of the five sons of Bhai Gopi Chand and Mai Mulan Devi, a Sahijdhari Sikh couple of the village of Harial in Gu|jarkhan tahsil, Rawalpindi district (now in Pakistan). His father died in 1901 and his brothers, Ganga Singh and the one who became famous as Master Tara Singh, took charge of him and supported him through school. After his primary classes in the village school, Niranjan Singh came to Amritsar where he matriculated at the Khalsa Collegiate School and passed his M.Sc. (chemistry) from the Khalsa College in 1916.
TATT KHALSA, lit. the Real or Pure Khalsa, as against the followers of Banda Singh Bahadur who came to be called Bandai Khalsa, was one of the factions in the schism which arose among the Sikhs after the passing away of Guru Gobind Singh. Guru Go bind Singh, while sending Banda Singh to the Punjab in 1708 to lead the Sikhs, had abolished the line of living Gurus bequeathing spiritual guruship to Guru Granth Sahib. Banda Singh in the flush of initial victories made some innovations which appeared heretical to the orthodox Khalsa.
