Marcis (age 19 – 23) provided financial support for the remarkable study of the Holocaust “Riga Ghetto List (1941–1943)” done by Tamara Zitcere. Zitcere’s research was a unique Holocaust study regarding its scope and content. In addition, he also supported her in other research studies about victim names from World War II in Latvia.

Years later, Marcis donated two holocaust related artworks, “Landscape Scene” (2006) and “Rumbula” (2003), to the Howard Gotlieb Archival Research Center in Boston University, USA, the archive of Nobel Prize winner Elie Wiesel. Shortly after the donation, he received a personal thank-you letter from Elie Wiesel.

In 2007, the Latvian Integration Foundation awarded Marcis the Society Unity Prize ‘For Contribution to Promoting Equal Opportunities’ for his support of the Holocaust studies’ “Riga Ghetto List”, for which he currently remains the youngest recipient at 23.

In 2011, Marcis handed over 680 testimony forms of Holocaust Victims’ Names to Yad Vashem in Jerusalem, Israel. All the 680 testimony forms were filled out by Zitcere based on her research about each Jewish victim in Riga Ghetto.

In 2015, his afterword was published in the new addition of the biographical book, “I Survived Rumbuli” by Frida Michelson (Author). The book offers a personal story about the Nazi occupation of Latvia and the Germans’ execution of over 30,000 Jews in the Rumbula’s forest near the city of Riga.
