According to the biographical introduction ,what challenges did the author ,Richard Wright have to overcome ?

Critics often describe the novel as a superb example of subtlety-crafted narrative describing Wright's journey into adulthood. Many critics question as to whether the book should be considered pure autobiography, particularly because they doubt the accuracy of Wright's recollection as well as because of its novelistic style. But it is agreed that the book monumentalizes an important piece of American, as well as African-American, history. Black Boy celebrates Wright's talent for narrative in its description of the brutal South from the black perspective between 1900 and 1945.
