In the vibrant world of post-Independence Bombay, a German art critic named Rudolf von Leyden played a pivotal yet overlooked role in shaping modern Indian art. Arriving as a refugee from Nazi Germany, Rudi soon became a tireless champion of India’s emerging avant-garde painters.

The Catalyst captures the critic’s monumental influence on artists like Ara, Husain, Raza, and Souza—the audacious pioneers who rebelled against academic styles to forge a bold new artistic vision for a nation reborn.

Through his perceptive reviews, Rudi encouraged the raw talent and electrifying experiments of these artists, then struggling on the fringes. The guidance he provided along with his European compatriots, Walter Langhammer and Emanuel Schlesinger, introduced the Progressive painters to international modernism, inspiring them to break free.

Beyond critical advocacy, Rudi’s generosity and networking fostered patronage for impoverished talents like K.H. Ara. His vision helped establish seminal Indian art institutions. This incisive critic recognized the genius of the Progressives long before the world took notice.

Pieced together from extensive interviews and archival material, this book provides a ringside view into an efflorescent period that forever changed the course of Indian art. It reveals Rudi’s warm relationships with the artists, especially his profound friendship with Krishen Khanna.

An immersive narrative, the book paints a vivid portrait of a man whose legacy continues to inspire.
