Jonny Steinberg is a South African writer and scholar.
 He is the author of several books about everyday life in the wake of South Africa’s transition to democracy.
 Two of them, "Midlands" (2002), about the murder of a white South African farmer, and "The Number" (2004), a biography of a prison gangster, won South Africa’s premier non-fiction award, the "Sunday Times" Alan Paton Award.
 In 2013, he was among the inaugural winners of the Windham-Campbell Literature Prizes, awarded by Yale University.
 Steinberg’s books also include "Three-Letter Plague" ("Sizwe’s Test" in the United States), which chronicles a young man’s journey through South Africa’s AIDS pandemic.
 It was a "Washington Post" Book of the Year and was shortlisted for the Wellcome Trust Book Prize, among others.
 Steinberg is also the author of "Thin Blue" (2008), an exploration of the unwritten rules of engagement between South African civilians and police, and "Little Liberia: An African Odyssey in New York" (2011), about the Liberian civil war and its aftermath in an exile community in New York and described as an "extraordinary, stylistically varied mix of reportage, history and biography".
 Steinberg's 2015 book, "A Man of Good Hope", was described as "superb" by "Observer" reviewer Ian Birrell, who wrote: "On the surface, it is simply the biography of a lonely young migrant who dreams of a decent life, hardening his shell and hustling to survive in hostile human environments.
 Yet it is really an epic African saga that chronicles some fundamental modern issues such as crime, human trafficking, migration, poverty and xenophobia, while giving glimpses into the Somali clan system, repression in Ethiopia and lethal racism in townships."
