NEW YORK (AP) _ An award-winning historian and a managing editor for projects and investigations at Bloomberg News have been elected to the Pulitzer Prize Board, which hands out the most well-known awards in journalism.

 

Columbia University, which administers the prizes, announced the elections of Steven Hahn and Robert Blau on Wednesday.

Hahn, a professor at the University of Pennsylvania, has explored African-American history, as well as issues of slavery and emancipation. He won the Pulitzer Prize for history in 2004 for his book, “A Nation under Our Feet: Black Political Struggles in the Rural South from Slavery to the Great Migration.''

Blau joined Bloomberg News in 2008, after working at The Baltimore Sun and the Chicago Tribune. At Bloomberg, he has overseen investigations on subjects including the Federal Reserve, end-of-life care and the gold mining industry.

While at the Tribune, the projects team Blau put together won the 2001 Pulitzer Prize for Explanatory Reporting for “Gateway to Gridlock'' about failures in the airlines industry.
