Cremers  has published numerous articles in international magazines, and was the codeveloper of a self-audit software tool with which museums are able to investigate their security and safety. Thus far Cremers is the first non-American to have received the prestigious Burke Award for the protection of cultural property.  His publication about emergency management in museums is a standard in the Dutch language world. At the moment Cremers is working on a new initiative to build a museum in Athens, Greece and is active in 17 museums on six islands in the Dutch Caribbean, teaching and training museum workers.

He has published widely on archaeological ethics, often with Dr Christopher Chippindale (University of Cambridge). Their research has promoted the material and intellectual consequences of looting. Gill has provided a commentary on the impact of such activity through his research blog, “Looting Matters”. This research has formed part of the effort to restore antiquities to Italy and Greece in the wake of the “Medici Conspiracy”.

He has studied more than 2,500 works of art and historic buildings, ranging from Leonardo Da Vinci's "Last Supper” and Botticelli's "Allegory of Spring", to Caravaggio’s “Medusa”. Founder and Scientific Director of EDITECH (Electronics, Diagnostics and Technology) in 1977, the first center for authenticating works of art in Italy.

Blanca Niño Nortonhas participated in workshops in Italy with the Carabinieri, and lectured in Argentina, Roma, Paraguay, El Salvador, Honduras, Mexico, Costa Rica, Cuba, Dominican Republic, and Colombia. With the Carabinieri TPC especially with Dr Pastore, Blanca Niño Norton was able to do important training in Guatemala. Through this collaboration with the Carabineri TPC they conducted 4 courses for more than 80 people, each with the support of the Ministry of Foreign Affairs of Italy and Ministero per i Bieni Culturale. 

Duncan Chappell’s publications include two coedited texts: Crime in the Art and Antiquities World. Illegal Trafficking in Cultural Property (2011) Springer: New York (With Stefano Manacorda) and Contemporary Perspectives on the Detection, Investigation and Prosecution of Art Crime (In Press) Ashgate: London (With Saskia Hufnagel). He has also had published a number of journal articles and book chapters on various aspects of art crime including fraud and fakery in the Australian Indigenous art market; the impact of corruption in the illicit trade in cultural property; and the linkages between art crime and organized crime.

In addition to his research and writing on art crime Duncan Chappell has acted as an expert in regard to court proceedings involving art crime and also been a strong supporter of  measures to enhance public awareness of the evils of looting behaviour and to strengthen the engagement of law enforcement agencies in investigation and prosecuting those responsible. In his present capacity as Chair of the International Advisory Board of the Australian Research Council Center of Excellence in Policing and Security, he has sought to foster a far more proactive approach to the prevention and detection of art crime both in Australia and its neighbouring countries within the South East Asian region.

Under Mr. Esterow's direction, ARTnews became the first magazine to consistently apply rigorous standards of investigative reporting to the art world.  Mr. Esterow received a special award for lifetime achievement from the College Art Association, the national organization of educators, artists, art historians, curators, critics, and institutions in 2003. He was cited for “his exceptional contributions to art journalism and investigative art reporting” and for having “overseen the magazine’s financial success while enhancing its reputation and influence in the visual-arts community and beyond.”

In Italy and abroad, he has covered the “Six Day War” (1967) and the war in Lebanon (1982); the death of Mitterrand and the election of Chirac; the murder of Rabin; the voyages of Pertini, Cossiga and Scalfaro, the ascension of eight italian governments and two Popes; the trials of Piazza Fontana, the Lockheed scandal, the Ardeatine massacre and the “Mani Pulite” political corruption scandal of the 1990s in Italy.  Since 1980, he has been dedicated to writing about cultural heritage protection, with an emphasis on historic preservation not only in Italy, but worldwide.

AUSA Levin pioneered the use of federal forfeiture laws to recover and return stolen art and cultural heritage property. The SDNY Asset Forfeiture Unit has initiated dozens of proceedings under the forfeiture laws -- seizing and returning artwork and cultural property to the persons and nations who rightfully own them.  Notable examples include the forfeiture and repatriation of stolen paintings by Lavinia Fontana, Jean Michel Basquiat, Roy Lichtenstein, Serge Poliakoff, Anton Graff and Winslow Homer; drawings by Rembrandt and Duhrer; an Etruscan bronze statute dated circa 490 B.C.; an antique gold platter dated circa 450 B.C.; a rare Mexican manuscript; a medieval carved wood panel which was originally inside the historic Great Mosque in Dvrigi; an Ancient Hebrew Bible owned by the Jewish Community of Vienna and stolen during the Holocaust and most recently, a Tyrannosaurus Bataar skeleton looted from the Gobi desert in Mongolia.

As her early career progressed Blanca Niño Norton became the Vice President of the International Committee of CIAV within ICOMOS and worked on the international charter for its preservation.   During the early eighties she served to create ICOMOS Guatemala.

Blanca Niño Norton became motivated in this field having attended a private party once in Northern Italy where the owner of the house was proud of the stolen part of a column he had in his living room. It was a Guatemalan piece and she felt as if the object was stolen directly from her. Strongly motivated Blanca Niño Norton started working against illicit traffic of cultural property in 2000 and received a grant from the Getty Conservation Institute as a guest scholar. Since then she has also participated in the creation of the office of International Cooperation in the Ministry of Culture in Guatemala and created the office Against Illicit Traffic with the direct support of the Guatemala ministry.  This office was established to enhance communication at the ministry between Guatemalan Customs, the FBI, ICE, the Carabinieri TPC, and Scotland Yard.  In this capacity, she served as principle advisor for the Guatemalan Minister of Culture. In furtherance of that Blanca Niño Norton participated at the international meeting of UNESCO in Cambodia on the convention against illicit traffic of cultural property.  During this time Guatemala signed agreements with UNIDROIT, and the second protocol of Haya; becoming the first country in the region to have signed all of the international cooperation agreements.

Among many cases, he considers most memorable the raids at the summer residence of Dr. Marion True (former curator of antiquities at the Getty Museum) and at the premises of the top illicit antiquities dealers in the world, Robin Symes-Christos Michaelides, in the Cyclades, where the famous archive was discovered.  Over the last five years (2007-present), Tsirogiannis has been identifying looted and ‘toxic’ antiquities at the most prominent auction houses (e.g., Christie’s, Sotheby’s and Bonhams) and galleries (e.g., “Royal-Athena Galleries”), as part of a project with the renowned academics Professor David Gill (University Campus Suffolk) and Dr Christopher Chippindale (University of Cambridge). Some of the results of his research have been already demonstrated in The Journal of Art Crime (“Polaroids from the Medici Dossier: Continued Sightings on the Market”, 2011:27-33, with Professor David Gill). This part of his research has contributed to the withdrawal of antiquities (e.g., Bonhams case, April 2010) and to the disclosure of many scandals in the field (e.g., Christie’s June 2010, April 2011, December 2011). Tsirogiannis’ primary aim is to notify governments to retrieve their stolen cultural property and to raise public awareness regarding antiquities trafficking, through media coverage of these cases.

Losing his apartment near the World Trade Center on September 11, 2001, he joined a counter-terrorism task force in Afghanistan, where he received a Bronze Star for actions against al-Qaeda. He then served in the Horn of Africa and three tours in Iraq—leading the investigation into the looting of Iraq’s National Museum—before deploying again to Afghanistan in 2009. Exposing the link between antiquities trafficking and terrorist financing, and presenting those findings to the United Nations, Interpol, British Parliament, and the Peace Palace in The Hague, he received a National Humanities Medal from President Bush for his work recovering more than 6,000 of Iraq's treasures in eight countries.  He holds a classics degree from Bucknell University; law degree and master’s in Classics from Columbia University; and master’s in Strategic Studies from the Army War College. Returning to the DA’s Office in October 2010, he continues the hunt for stolen antiquities. All royalties from his book, Thieves of Baghdad, are donated to The Iraq Museum.

In the past six years, the Southern District of New York has forfeited nearly $6 billion in crime proceeds. Ms. Levin pioneered the use of federal forfeiture laws to recover and return stolen art and cultural heritage property.

Tsirogiannis, took his first degree in Archaeology and History of Art at the University of Athens and began his career as an archaeologist working for the Greek Ministry of Culture.  One morning in August 2004 he reported that his world changed when he got a phone call from the headquarters of the Athens police asking him to accompany them on a raid of a monastery where antiquities without any collecting history had been found. The Greek judicial system found the monks innocent – but it was a clearly problematic case that opened his eyes to the problems of trafficking. While in Greece, Tsirogiannis continued to work for the police as an unpaid volunteer, frequently escorting authorities on raids throughout Greece and identifying looted antiquities, while keeping his day job at the Ministry of Culture.  When his work with the police grew, he was offered a post with the Ministry of Justice. As an expert trusted by the authorities, he was directly involved in a series of high-profile investigations by specialist teams from the Greek and Italian police, researching archives of looted objects that had made their way along a clandestine network of looters, middlemen, famous auction houses and high-profile dealers working closely with top collectors.  The most notorious of these raids was that on the Robin Symes-Christos Michaelides summer residence in the Cyclades, where the authorities found an archive of professional photographs that recorded numerous looted and smuggled antiquities from nearly all the world’s ancient civilizations.

Many greetings from Nairobi. I will now try to answer some of the questions you raised. First let me recognize the good work ARCA is doing, and to thank the membership for the award that I feel is a great privilege to me and to Africa as a whole. As an archaeologist and a heritage professional, I have spent a lot of my working life in museum and museum-related fields. I have dealt with the protection of works of art as a field archaeologist working on the Kenyan coast, as head of Coastal Museums Programmes, as Deputy Director of the National Museums of Kenya and, subsequently, from 1999-2002, as Director General of the National Museums of Kenya. The museum, apart from hosting the Gallery of East African Contemporary Art, was also in charge of all other heritage in the country, including the Mijikenda Kayas, where many of the vigango were stolen from in the past. 

I got involved with the vigango issue when I was still at the Coast of Kenya, working as the Coastal Archaeologist as well as Head of the Museums there. During that time we had to deal with thefts not only of the vigango but also the illegal sale and purchase of Swahili cultural materials such as chairs, doors and jewelry — all that qualify as works of art. With the cooperation of law enforcement agencies, we managed to apprehend a number of dealers who, unfortunately, due to the leniency of the law, often managed to get away with only small fines by way of penalty. However it was a lesson to others. 

As for the return of the vigango to Kenya, this happened after I left the museum. However I started the process of the return by working with two scholars from the USA who had worked on the Kenyan coast and knew the vigango and the families from whom they had been stolen. We basically blew the whistle, as well as contacted these institutions during my time at the museum, to inform them that we knew they had these items and, as a country, we wanted them back. As my successors at the museum continued to follow up through official channels with the institutions, I continued to write articles using these as examples of illicit and immoral acquisitions. In the end, both the Kenyan government, as well as the concerned institution, took the action to return two vigango. Since then, many have been returned.
