About Callie DanielsDavid SchneiderJohn HornsbyMargaret Lial

Marge Lial (late) was always interested in math; it was her favorite subject in the first grade! Her desire to educate both her students and herself inspired the writing of numerous best-selling textbooks. Marge who received Bachelor's and Master's degrees from California State University at Sacramento was most recently affiliated with American River College. An avid reader and traveler Marges travel experiences often find their way into her books as applications exercise sets and feature sets. She was particularly interested in archeology. Trips to various digs and ruin sites produced some fascinating problems for her textbooks involving such topics as the building of Mayan pyramids and the acoustics of ancient ball courts in the Yucatan.   When John Hornsby enrolled as an undergraduate at Louisiana State University he was uncertain whether he wanted to study mathematics education or journalism. His ultimate decision was to become a teacher and now after more than twenty-five years of teaching at the high school and university levels and fifteen years of writing mathematics textbooks both of his goals have been realized. His love for both teaching andmathematics is evident in his passion for working with students and fellow teachers as well. His specific professional interests are recreational mathematics mathematics history and incorporating graphing calculators into the curriculum. John's personal life is busy as he devotes time to his family (wife Gwen and sons Chris Jack and Josh). He has been a rabid baseball fan all of his life.
