Who was Dasganu Maharaj and what were his literary contributions concerning Sai Baba?

Shri Dasganu Maharaj is described in Chapter 0 as a foremost modern poet who was worthy of Shri Sai Baba's grace. He authored two biographies of Baba. The first is found in his Bhaktalilamrut (Chapters 31, 32, 33), and the second is in his Bhaktisaramrut (Chapters 52, 53). While the text praises these works as undoubtedly excellent and heart-touching, it also emphasizes that they are very short. The source mentions that the stories within them are largely the same as those in the Shri Sai Satcharita, but Dasganu also included commentary on the state of the country, which Annasaheb did not.
