At the Maryland Historical Society, they're calling it the Great Cupcake Caper.
Before being arrested by police on Saturday and charged with stealing dozens of historical documents, author and collector Barry H. Landau had brought cupcakes for the center's staff. They figure he was trying to ingratiate himself with the staff, much as he has for decades with political and Hollywood elite.
And it may be a calling card of sorts. As the investigation into the thefts continued to broaden Tuesday, officials of at least one other state historical society said they had been visited multiple times in the past by Landau and his alleged conspirator, who brought Pepperidge Farm cookies for the staff and aroused suspicions with their "odd" behavior.
Word of the arrests has set off a ripple effect among the historic preservation community, with the FBI requesting that other museums and libraries review their logs to see if Landau and 26-year-old Jason Savedoff had been visitors and, in turn, made them potential victims.
Landau is a renowned collector, reputed to have the largest collection of presidential memorabilia outside of museums and the presidential libraries. The former White House protocol officer has claimed to have 1 million artifacts in his Manhattan apartment on West 57th Street.
The director of the Maryland Historical Society confirmed that the pair had previously visited its Baltimore library in June, and authorities were working to account for documents that were checked out during that visit.
The incident has sparked renewed attention to securing priceless and historic artifacts at museums and libraries.
"In historic preservation circles, it's a problem that they've been trying to deal with for some time, and these situations bring it right to the forefront," said Joseph M. Coale, the former president of Historic Annapolis, who served on the board of the Maryland Historic Trust for 25 years. "Maryland has an interesting and unique history that's given great credibility by a lot of these documents, and these guys wanted to rob us of that. As a Marylander, I'm rather incensed about it."
Authorities declined to discuss the next steps in the investigation, but agents from the National Archives were observed leaving the Maryland Historical Society's Monument Street location around lunchtime Tuesday, boxes under their arms, as an FBI agent with a gun on his hip reviewed documents in the library where the crimes are alleged to have occurred.
"We're trying to determine how widespread this might be," said Richard Wolf, a spokesman for the FBI in Baltimore.
Landau and Savedoff, charged with one count of theft over $100,000, were initially held on $1.5 million bond, but a judge revised that to no bond at a hearing Monday, which Landau's attorney, former federal prosecutor Andrew C. White, called "outrageous."
"Mr. Landau is one of our nation's most well-respected presidential historians, and I think it's outrageous that he's being held without any bond in a property theft case in which none of the allegedly stolen property ever made it out of the historical society," White said. "Clearly, there's a breakdown in the judicial process."
White said he was filing a habeas corpus petition in Baltimore Circuit Court to obtain bail for Landau.
In Philadelphia, Lee Arnold, senior director of the library and collections at the Historical Society of Pennsylvania, said Landau and Savedoff — using the name "Jason James" — had visited more than a dozen times since December, identifying themselves as uncle and nephew. Landau, according to his website, is working on his second book.
Landau introduced himself as a scholar and donated a copy of his first book to the society, and each time he came bearing cookies. But when officials tried to write him a thank-you note, it was sent back as undeliverable. An email address Savedoff gave also appeared to be invalid. Staff became suspicious and called a meeting, and planned to check their driver's licenses upon the next visit.
Of Landau, Arnold said: "He certainly was very personable. He had class. He knew how to conduct himself in a research library." But Savedoff, of whom little is known, was "rough around the edges" and "repeatedly asked naive questions," he said.
"He never understood what we were saying," Arnold said.
Staff members were reviewing footage from surveillance cameras to see if there is any evidence of theft. Kim Sajet, the Pennsylvania society's president and CEO, said they are filling out a report for the FBI.
The FBI issued a request for information, saying that Landau and Savedoff may have used "their true names or permutations thereof." History buffs were trying to get the word out more organically as well — Jennifer Ferretti, the digitization coordinator for the MHS, put out a message on Twitter saying "Please alert all archives (esp. on the East Coast) about Barry Landau! He visited more places than just MdHS."
Meanwhile, Landau's past continued to raise questions. WJZ-TV confirmed that Landau, who shares a name with a retired producer for CBS' "60 Minutes," had attended auctions and collectible shows by showing a media credential for the national network, which issued a cease-and-desist letter to him after it found out.
Rex Stark, a dealer, collector and recognized authority on Americana, said he had known Landau for 20 years and said he has the "premier" collection of presidential inaugural tickets, invitations, menus and programs. He said Landau often name-dropped his various connections, so much so that Stark said he got "tired of listening to it a lot of the time."
Stark said that he was not aware of Landau ever acting as a dealer, though he said he contacted him two months ago that he was "interested in selling things," and had mentioned rare and expensive autographs of Beethoven and Marie Antoinette.
"We follow what goes on in the industry, in this world," Paul Brachfeld, the inspector general for the National Archives, said on Monday before his agency became involved in the investigation. "If they do it one place, they may very well do it in another."
Brachfeld declined comment Tuesday on the steps his agency was taking or why it had become involved.
At the Maryland Historical Society, President Burt Kummerow gave a reporter a tour of a new exhibit set to open soon that shows off War of 1812 artifacts and paintings by Charles Willson Peale, among other items. The museum, located two blocks west of Baltimore's Washington Monument, mixes historically significant items with modern architecture and has the largest collection of Maryland history in the world.
Kummerow said records show that Landau and Savedoff had visited the historical society in June. He would not comment on whether other items had been taken. "We're checking that out," he said.
Though Kummerow said the society has been growing, it remains short on funds and staff. That puts it in a potentially vulnerable position as it allows access to its collection of 7 million documents contained within its library.
Coale, the former board member for the Maryland Historic Trust, said he doesn't believe archives will be able to continue to allow access to original documents. "They don't have the staff to do it, especially nowadays with societies more or less operating with skeleton crews," he said.
But Kummerow says his staff is also not in a financial position to digitize its archives or provide photocopies of the volumes of material researchers may want to see.
Kummerow is reassured, however, that the weekend theft was detected by staff members, who called the police officers that ultimately found five dozen documents that had been checked out by Landau and tucked into a laptop case inside a locker belonging to Savedoff.
"The proof is in the pudding — we caught them," Kummerow said. "The library really did its job."
