Hiltrud Engel-Siegel (1948-2000)
A graveside service will be held tomorrow for Hiltrud (Engel) Siegel of Sudbury, a former biological research assistant at Harvard University, who died at her home Saturday of cancer. She was 52.
Mrs. Siegel was born in Hofheim, Germany. She grew up in the village in Kriftel, where her father ran the first test garden in the country to grow broccoli and other nonnative vegetables.
In 1973, she went to Harvard to help research the social behavior of ants. She had previously studied in Frankfurt.
