The third edition of his well-regarded textbook, A History of Mathematics: An Introduction, appeared in 2008. A brief version of this text was published in 2003.  Katz is also the editor of The Mathematics of Egypt, Mesopotamia, China, India and Islam:  A Sourcebook, published in 2007. Professor Katz has written many articles on the history of mathematics and its use in teaching and has spoken widely on the subject.  He presented an invited lecture, “Stages in the History of Algebra with Implications for Teaching,” at ICME-10 in Copenhagen in 2004.

He has edited or co-edited three books dealing with this subject, Learn from the Masters (1994) and Using History to Teach Mathematics (2000), and Recent Developments on Introducing a Historical Dimension in Mathematics Education (2011).  He also co-edited two collections of historical articles taken from journals of the Mathematical Association of America in the past 90 years, Sherlock Holmes in Babylon and other Tales of Mathematical History (2004) and Who Gave You the Epsilon and Other Tales of Mathematical History (2009). 

He has directed two NSF-sponsored projects that helped college teachers learn the history of mathematics and how to use it in teaching and also involved secondary school teachers in writing materials using history in the teaching of various topics in the high school curriculum.  These materials, Historical Modules for the Teaching and Learning of Mathematics, were published on a CD by the MAA in 2005.  Professor Katz was the founding editor of Loci: Convergence, the MAA’s online magazine in the history of mathematics and its use in teaching, serving from 2004 until 2009.  Professor Katz is married to Dr. Phyllis Katz, a science educator, and has three grown children and six grandchildren.
