Elias Davidsson was born in Palestine in 1941. His parents were born in Germany but had to emigrate to Palestine due to the Nazi persecution of Jews.

Elias lived his first years Baq'aa, a neighborhood of Jerusalem, where Jews, Christians and Muslims lived in peace side by side. These early years left a deep mark on him. He lived in France, Germany and the United States until he settled finally in Iceland.

Elias settled in Iceland in 1962 and worked for over 20 years as computer programmer and systems engineer. At 1983 he quit work with computers and decided to return to his once-cherished field, music. After receiving a diploma as piano teacher in Switzerland, he returned to Iceland to work as a music school director, church organist, teacher, composer and arranger. He has published about 20 volumes of original compositions for musical education. These are widely used in Europe by music teachers and commercially available (see tonar-og-steinar.com).

In parallel to his professional occupations, Elias has for many years been involved in activism and research regarding social and global justice, peace, anti-racism and human rights. He is co-founder of the Association Iceland-Palestine and a supporter of a democratic State in the whole of historic Palestine for Muslims, Christians and Jews. He regards himself as an anti-Zionist and rejects the existence of a Jewish state as incompatible with human rights norms. His writings include articles on multinational corporations, the IMF and the World Bank, the Palestine question, Zionism, economic sanctions and international law (see writings by Elias Davidsson ). In 2002, Elias started research on the events of September 11, 2001 and founded the Icelandic chapter of the 9/11 truth movement.

Elias Davidsson moved from Iceland to Germany in July 2008.
