who did Gandhiji meet to collect facts about the dispute between the sharecroppers and landlords?

Gandhi went to Muzzafarpur which was en route to Champaran to obtain more complete information about the conditions than Shukla was capable of imparting. He sent a telegram to Professor J.B. Kripalani, of the Arts College in Muzzafarpur, whom he had seen at Tagore’s Shantiniketan school to get the facts about the case.
