Ulla Hadar | Researcher

Ulla Hadar leads Israeli engagement efforts for The Butterfly Project, where she works to preserve and share the stories of Holocaust victims through education and remembrance. Born in Denmark, Ulla earned a B.A. in Economics from Copenhagen Business School in 1982. That same year, a visit to Israel sparked a lifelong connection to the country, where she ultimately settled with her husband and raised a family in Kibbutz Ruhama.

For 25 years, Ulla worked as a senior designer of integrated circuit boards before pivoting to a new path focused on education and community engagement. In 2012, she founded and ran a bike school for children and adults on her kibbutz, reflecting her passion for sport, creativity, and lifelong learning.

Ulla’s connection to The Butterfly Project began in 2008 through her involvement in installations across Israel. In 2017, she began researching the family histories of Israeli Holocaust survivors, helping individuals uncover the fate of loved ones lost in the Shoah. This work evolved into a deep commitment to building The Butterfly Project’s bio card library, which documents the lives of children murdered in the Holocaust.

Today, Ulla collaborates closely with Nicole Nocon in Germany to research and write biographies of German child victims. Together, they are expanding The Butterfly Project’s reach across borders, ensuring that remembrance and education remain at the heart of Holocaust memory work.
