Rustom Pestonji Masani

Rustom Pestonji Masani (1876–1966) was an Indian Parsi author whose work ranged across history, religion, biography, and social thought. Library records and book catalogs consistently link his name to titles such as Zoroastrianism: The Religion of the Good Life, Britain in India, The Five Gifts, and Folklore of Wells, showing both the breadth of his interests and his gift for writing for non-specialist readers.

He is best known for Dadabhai Naoroji: The Grand Old Man of India, a major biography of the pioneering nationalist leader. Later scholarly work has described Masani's book as detailed and long important to the study of Naoroji, which helps explain why it remains the work most closely associated with his name.

Sources found during this search also style him as “Sir Rustom Pestonji Masani,” indicating that he was knighted. I was able to confirm his books and his standing as a biographer and public-minded writer, but I did not find a reliable page with a clear, verifiable portrait image to use here.
