**Karen Dee Michalowicz** died on July 17, 2006 at the age of 63. She was a nationally recognized mathematics teacher at the Langley School in McLean, Virginia, having received the Presidential Award for Mathematics Teaching in 1994. Karen was especially interested in the use of history in the teaching of mathematics. In that role, she co-directed the NSF-sponsored, MAA administered grant program, *Historical Modules for the Teaching and Learning of Mathematics*, beginning in 1998. That program involved about twenty-five college and high school teachers of mathematics, who produced such a large amount of material for teaching mathematics using history that the MAA was forced to publish it as a CD. In 1998, she was also invited to participate in the study group on History in Mathematics Education, organized by the International Commission on Mathematical Instruction. After an intensive week of discussions, the group ultimately co-authored the ICMI Study, *History in Mathematics Education*, which appeared in 2000. Karen was in charge of the group writing the chapter on "History in support of diverse educational requirements — opportunities for change". Over the years, she had amassed a huge collection of mathematics texts from the nineteenth century and earlier, a collection whose contents she enthusiastically shared with students and colleagues in many presentations at national and international meetings. She will be greatly missed by her numerous friends and colleagues in the MAA, the WME, the NCTM, and the Benjamin Banneker Association, among others.
