Gr 6-10-These pedestrian biographies portray the working lives of two 20th-century scientists. Both provide clear narratives about the way the inventors progressed from initial inspirations through many false trails to eventual success, despite certain obstacles. In an apparent effort to attract readers, the authors wring every bit of drama they can from their subjects' lives. But accounts of conflicts with parents and bouts of depression will not be enough to attract students' interest. Banting was quite well known in his time, and several books have been written about his life for this audience (all are out of print). Carothers's life was not as well documented. Bankston quotes several biographies, but Gaines attributes emotional states to her subject without any documentation. Neither book lists sources. Graphically, both titles are very ordinary, with large blocks of type unbroken by supplemental material. The black-and-white photographs are well reproduced. Average-quality choices for reports.-Jonathan Betz-Zall, City University Library, Everett, WA Copyright 2001 Cahners Business Information.
