On October 1, 2007, Dewey Ballantine merged with LeBoeuf, Lamb, Greene & MacRae to form the combined firm of Dewey & LeBoeuf LLP. The combined firm had over 1,400 attorneys in 27 offices around the world. The headquarters for the newly merged Dewey & LeBoeuf was placed in the legacy Dewey Ballantine offices in the Calyon Building in Midtown Manhattan. The successor firm, Dewey & LeBoeuf, collapsed in May 2012 due to debt resulting from a poor partner recruiting and compensation strategy, which led to and was exacerbated by a talent exodus.
