ĪSHAR SIṄGH GRANTHĪ, BHĀĪ (1881-1921), one of the Nankāṇā Sāhib martyrs, was born at Bahoṛū village in Amritsar district in 1881, the son of Bhāī Atar Siṅgh and Māī Nihāl Kaur. His schooling was interrupted owing to his father's death. But the desire to learn was so strong in him that at the age of 26, he joined the Khālsā Prachārak Vidyālā, Tarn Tāran, and spent four years there studying Sikh history and philosophy, besides practising kīrtan. In 1915 he joined the Khālsā school at Jhabāl in Amritsar district as a Punjabi teacher. Īshar Siṅgh returned to his native place to become the custodian of the village gurdwārā. When Bhāī Lachhmaṇ Siṅgh gave the call for the liberation of Gurdwārā Janam Asthān at Nankāṇā Sāhib, he joined his jathā and fell a martyr in the shower of bullets rained upon it by the local keeper of the shrine and his men on the morning of 20 February 1921.
