Swami Sadananda Das (Sanskrit: स्वामी सदानन्द दास, IAST: Svāmī Sadānanda dāsa; 1908–1977) was born as Ernst-Georg Schulze in Germany. He met Swami Bhakti Hridaya Bon, a disciple of Hindu spiritual reformer Bhaktisiddhanta Sarasvati Thakura. Sadananda received diksa or formal initiation into the Gaudiya Vaishnava tradition through Swami Bon from Sarasvati, and later received the name Sadananda Das by Sarasvati directly after he had joined the Gaudiya Mission in Calcutta, India. He was one of the first known individuals who was not of Asian origin to embrace the Gaudiya Vaishnava tradition.
