Who gave the famous slogan 'Back to Vedas'?

The slogan 'Back to Vedas' (Vedo Ki Aur Lauto) was given by Swami Dayananda Saraswati, the iconic social reformer and founder of the Arya Samaj (established in $1875$). He believed that Hindu society had corrupted itself by moving away from the pure, egalitarian teachings of the original Vedic texts.
