Money woes are forcing the National D-Day Memorial Foundation in Bedford to lay off 11 of its 24 employees, President William McIntosh said Monday.

The memorial employees, some full time and some part time, were told last week, McIntosh said, adding that they've known their jobs were in jeopardy since February.

"They were told that everybody's position was vulnerable, depending on revenues and the economy and the usual variables that nonprofits have to contend with," McIntosh said.

The layoffs are effective Dec. 1. McIntosh said the foundation will also soon announce another cost-cutting measure -- a winter operating schedule that will require visitors to call ahead before touring the memorial site.

The memorial, which recognizes the June 6, 1944, Allied landing at Normandy, France, during World War II, has a $2.2 million annual operating budget but is running out of money. The foundation receives about $600,000 a year in ticket sales, tours and gift shop revenues; the rest comes from contributions.

The foundation is asking the federal government to take control of the memorial, and the National Park Service is studying whether the 8-year-old memorial can be put under its control under the federal Antiquities Act. McIntosh, however, said he has been informally told the answer to that is no.

The park service has said it may suggest other options through which the memorial can continue to operate.

Meanwhile, President Obama signed legislation last week ordering the U.S. secretary of the interior to conduct a full study of whether there is a role the federal government can play to keep the memorial open. That study could take two years to complete.
