With a full summer slate, the next event at the Longfellow National Historic Site will be a “Salute to John Updike.” The June 28 event, which starts at 4 p.m., features poets X.J. Kennedy and F.D. Reeve, along with journalist Christopher Lydon, who knew Updike from his TV and radio interviews. The program is free and open to the public. It will take place on the east lawn of the Longfellow National Historic Site, 105 Brattle St., Cambridge, Mass. The program is sponsored by Elena Seibert, and seating is limited.

Longfellow House is a natural historic site that, in addition to being the residence of the 19th-century poet, also served as headquarters for Gen. George Washington during the siege of Boston from July 1775 through April 1776.
