David John Etzwiler, 75, of Baraboo, died at home surrounded by his family, after a short but losing battle with cancer. David was born on Jan. 15, 1941 in Mansfield, Ohio, the youngest of three sons of Claude and Germaine Etzwiler. He graduated from St. Peter’s School in Mansfield, and went on to St. Joseph’s College, Rensselaer, Indiana, for a BS in Math. He spent a year as a Fulbright scholar in Tuebingen, Germany, then returned to the states to study at UW-Madison for an MS in Math. There he met Nijole Semenas, for whom he was the love of her life. They married on Dec. 26, 1964, and together went into the Peace Corps in Brazil. On returning home, they settled in Wisconsin and raised three boys. He taught in Hamburg, Germany for two years and took every opportunity to introduce the art and culture of Europe to his family. David began working at UWC-Baraboo/Sauk County in 1977, and retired from there in 2003, but continued as a volunteer tutor and teacher for many years. He was a member of the Sauk County Historical Society, the Al Ringling Friends, AMATYC (American Mathematical Association of Two-Year Colleges), and Madison Vilnius Sister Cities, and active in the Baraboo Community Scholarship Corporation, Zaibas Lithuanian Dancers, and the St. Joseph Church Choir.
