 Wonder was born Stevland Hardaway Judkins in Saginaw, Michigan, on May 13, 1950, the third of six children born to Calvin Judkins and songwriter Lula Mae Hardaway.He was born six weeks premature which, along with the oxygen-rich atmosphere in the hospital incubator, resulted in retinopathy of prematurity, a condition in which the growth of the eyes is aborted and causes the retinas to detach, so he became blind.When Wonder was four, his mother divorced his father and moved with her children to Detroit, Michigan, where Wonder sang as a child in a choir at the Whitestone Baptist Church.
