Independent filmmaker Ronald F. Maxwell, who directed the epic Civil War movies "Gettysburg" and "Gods and Generals," is scheduled to be the featured speaker at the first annual Fairfax County History Conference on Saturday at Frying Pan Park in Herndon.

The conference, whose theme is "People, Places and Preservation," is an attempt to generate interest in historical preservation. Its sponsors include the county's History Commission, Park Authority and Architectural Review Board and the Fairfax City Museum and Visitor Center.

Maxwell is now in pre-production on "Joan of Arc: Virgin Warrior" and is preparing for "Last Full Measure," the final part of his Civil War trilogy, according to an Internet biography. The conference, which is from 9 a.m. to 4 p.m., also will include:

* A panel discussion called "Preserving Our History," with Jean Federico, director of Historic Alexandria; Lynne Strobel, a land use lawyer; Francis Gary Powers Jr., founder of the Cold War Museum; Phyllis Walker Ford, president of the Franconia Museum.

* A luncheon with a preview of a video called "The Battle of Chantilly" made by local photographers Chuck Mauro and Bert Morgan.

* Small group sessions on historic places in a changing county, on lessons learned from preservation efforts at the former Lorton prison and on taking inventory of the county's historic sites.

* A trip to the nearby Frying Pan Meeting House, built in 1791. It recently was rededicated after an 18-month restoration, stabilization and documentation.

The conference will be at the Ellmore Farm Center at the park, 2739 W. Ox Rd.

The cost is $10, which includes a catered lunch; proceeds will go to the History Commission. Attendance is limited to 100 people.
