Tonight at 6pm, Howard Bryant will speak at the Boston Public Library. From the BPL website: 

Howard Bryant delivers a definitive biography of Baseball Hall-of-Famer Henry Aaron. Bryant's research here is exhaustive, but it only serves to add texture and context to Aaron's compelling story, which starts with an impoverished but proud Mobile, Alabama boyhood, then follows Aaron's long and steady trajectory as the greatest home-run hitter (if not player) of his generation, ending with Aaron's public and private responses to the breaking of his home-run record by Bonds in 2007.

Howard Bryant is the author of Shut Out: A Story of Race and Baseball in Boston, which was a finalist for the Society of American Baseball Research's 2003 Seymour Medal, and Juicing the Game: Drugs, Power, and the Fight for the Soul of Major League Baseball. He is a senior writer for ESPN.com and ESPN the Magazine; appears regularly on ESPN's The Sports Reporters, ESPN First Take, and Outside the Lines; and serves as sports correspondent for NPR's Weekend Edition Saturday.
