**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.
