Dvorah Barzilay-Yegar (born 1933) is an Israeli historian, who has carried out many years of scholarly research into the life and political activities of Chaim Weizmann, the first President of Israel.
Barzilay was brought up in Rehovoth, where she had her elementary and secondary education. She obtained her B.A. at the Hebrew University of Jerusalem, in the Faculties of History and Sociology. Barzilay served as a Lieutenant in the Israeli army's Department of History. When discharged, she obtained her M.A. at the Hebrew University in the Faculties of History and Jewish History. Following a period of research in England, she returned to Israel and was granted a Ph.D. Her doctoral work was on "A National Home for the Jewish People – The Concept in British Political Thinking and Policy Making, 1917–1923". At the same time, she studied at the Faculty of Education of the Hebrew University and was granted a Teaching Certificate. She then taught History at the secondary school in Rehovoth during 1958–1960.
In the years 1961–1974, Barzilay was a researcher and research editor on the Editorial Board of Weizmann's Letters and Papers, Jerusalem, and the Weizmann Archives in Rehovoth. In the years 1966–1969 she lived in London, where she was sent by the editorial board of Weizmann's letters and papers, to carry out research and to retrieve material at the British archives about Weizmann's activities during World War I, especially in connection with the Balfour Declaration. She also published articles on this subject. On her return to Israel, she edited Volumes VII and VIII of Weizmann's letters which were later published in Hebrew and English.
In the years 1974–1980 Barzilay was research director and editor of Samuel Tolkowsky's "Zionist Political Diary, London 1915–1919, on the Making of Balfour Declaration" published (in Hebrew) by the Institute of Zionist Research at Tel-Aviv University and the Zionist Library, Jerusalem.
In the years 1974–1985, Barzilay was research director and editor of the survey of archival sources of the history of British Mandate in Palestine, 1914–1948, a project sponsored and financed by the Israel Academy of Sciences and Humanities in Jerusalem, Israel (in collaboration with the British Academy). The results were later produced in a disk.
In 1979 Dvorah Barzilay married Moshe Yegar, an historian and diplomat in the service of Israel's Foreign Office, and eventually joined him on his Foreign Office postings as Consul General in New York, and ambassador in Stockholm and Prague. In New York she taught as Adjunct Professor at Queens College of the City University of New York, in Sweden she took part in academic conferences and in the Czech Republic she taught as Visiting Professor at Charles University in Prague and took part in academic conferences.
