Umaswati also known as Umaswami is the author of Tattvartha Sutra, one of the important Jaina scripture. The details of his life are controversial. He is claimed by both the Digambara and Svetambara sects as their own. A mathematician, he is thought to have lived around the 2nd century BC. It is likely that at this time no clear division of the Jain community had emerged, and thus both sects may be right in claiming him. He was conferred with the title of Acharya. The word Acharya is a title prefixed to the names the Jain spiritual leaders who are considered as one of the panch parmeshti's as per Navkar Mantra.
