Gundappa was born on 8 January 1903 in the village of Mathighatta in South India. His early education took place in Belur, Karnataka, where he immersed himself in the study of Sanskrit and the Vedas. By the time he completed his middle school education, Gundappa had already mastered the Sanskrit language. He later moved to Chikmagalur for his high school education, where his talent for composing original devotional poems in Sanskrit caught the attention of Abhinava Vidya Theertha Swami, the religious leader of Sringeri Sharada Peetham. Impressed by Gundappa's work, the Swami pledged to provide a monthly stipend to support Gundappa's college education.

Gundappa pursued his higher education at Mysore Maharaja's College, a hub of intellectual activity focused on India's liberation from British colonial rule. It was during this time that various movements advocating the rediscovery of India's cultural heritage gained momentum.

Gundappa, influenced by his mentor B.M. Sri and other literary giants like T.S. Venkataiah and A.R. Krishnashastry, became deeply committed to reviving Indian culture and literature. As advised by his mentor, Gundappa chose to learn Tamil as part of his master's degree curriculum in languages, aiming to reintroduce the Kannada community to its heritage through meticulous translations of literary works from Sanskrit, Tamil, and English.

Gundappa was married to Smt. Sharada of Akki Hebbal, and together they had seven children. Gundappa's daughters, Sumitra, Vimala, and Kamala, collectively known as the L.G. sisters, garnered fame for popularizing Kannada folk songs and light songs (Bhava Geethegalu) by contemporary poets like Pu Ti Narasimhachar and Bendre from a young age.^{[citation needed]}
