No, Dadabhai Naoroji is not the founder of Bharat Sevak Samaj. Bharat Sevak Samaj was founded by Dr. K. B. Hedgewar in 1950 as a social service organization aimed at promoting national integration and community development in India. Naoroji, known as the "Grand Old Man of India," was a prominent political leader and economist, but his contributions were primarily in the fields of politics and education rather than in the establishment of Bharat Sevak Samaj.
