Michael Blair, who has led Debevoise & Plimpton for more than a decade, is retiring at the end of this year. The firm has named Peter Furci, the co-chair of its tax department, as its next presiding partner, effective July 1.

Meanwhile, Nicole Mesard, deputy chair of the firm’s corporate department and member of its management committee, will ascend to deputy presiding partner, becoming the first woman to hold that firm role.
