Project Manager

Mrs. Michèle Sigg is the Project Manager for the Dictionary of African Christian Biography and has been working on the project since the New Haven office opened in October 2000. She moved to France with her missionary parents when she was eleven. After graduating from French public high school in France, she attended Covenant College in Tennessee. Following two years in the trilingual translation program (I.S.I.T.) at the Institut Catholique in Paris, she went on to complete a B.A. in French and Spanish at the University of Pennsylvania, as well as a Master's in French Literature. While at university she met her husband Sam, also from a missionary family, who grew up in Zaïre and France.

Before moving to New Haven, she worked as a translator and a French teacher at the university and high school levels. Working in coordination with Project Luke fellows and African scholars, she edits and incorporates all the DACB articles into the website. She serves as Webmaster and graphic designer as well as bi-lingual editor for the dictionary. She is also a potter and a writer of children's stories and plays. The Siggs now have three children, Johan, age 16, Annie, age 14, and Catherine, age six.

Office Assistant

Since 2006, Miss Becka Sisti has been the office assistant for the Dictionary of African Christian Biography. She is responsible for HTML coding for the Dictionary's articles, updating the Web site, maintaining the databases, and sending out mailings.

She is a member of Simchat Yisrael (Joy of Israel) Messianic Synagogue in West Haven, CT, a community where her Jewish identity and her belief in the Messiah, Yeshua, are not only compatible but intricately woven together. This congregation is her family and where her heart remains. She loves learning about Judaism, and keeping the traditions and holidays of her people. Her favorite kind of music is 1960s rock, especially the Beatles, but she listens to a wide variety, including traditional and contemporary Jewish music and show tunes. She also loves New York City, chocolate ice cream cones, tea and scones, British accents, peace signs, the color magenta, John Lennon, strawberries, and daisies.
