Doris Schattschneider

Doris was a math teacher.

She loved patterns. She studied how shapes fit together. This is called tiling.

One woman found new ways to tile. She was not a math teacher. Doris checked the new patterns. She saw they were right.

Doris helped tell the world about them. She even spoke about the woman in public. Everyone stood up to clap.

Doris also wrote books. She wrote about art and shapes. She helped make tools for math too.

She worked at a college for many years. She was a great teacher.

Doris Schattschneider is a famous math expert. She loves shapes and patterns. One special thing she studies is tiling. Tiling is when shapes fit together perfectly.

Doris helped a woman named Marjorie Rice. Marjorie was not a math teacher. She found new ways to tile with pentagons. A pentagon is a shape with five sides. Doris checked the work. She saw the new patterns were correct. Doris helped the world learn about them. At a big meeting, Doris introduced Marjorie. Everyone stood up to clap for her.

Doris also wrote many books. She wrote about the art of M. C. Escher. She also wrote about math tools. She helped make a tool called The Geometer's Sketchpad. This tool helps people learn math.

Doris was a teacher for 34 years. She worked at Moravian College. She won many awards for her work. She even became a fellow of the American Mathematical Society. This is a big honor for math experts.

Doris Schattschneider is a famous American mathematician. She spent many years teaching math at Moravian College. Doris is well known for studying patterns and shapes. One special area she studies is called tessellation. Tessellation is when shapes fit together perfectly without gaps.

She also wrote many books about the artist M. C. Escher. Her work helps people see the math in art. She even helped create a math tool called The Geometer's Sketchpad.

One of her most important jobs was helping another person. Marjorie Rice was an amateur mathematician from San Diego. Marjorie loved reading about how shapes tile a flat surface. In February 1976, Marjorie found a new way to tile with pentagons. A pentagon is a shape with five sides. Marjorie used her own special way to write down her ideas. She mailed her new patterns to a man named Martin Gardner.

He sent the work to Doris to check it.

Doris was an expert in tiling patterns. At first, she was skeptical about the new findings. She looked at the shapes very carefully to be sure. Doris found that Marjorie's new pentagon patterns were correct. She helped Martin Gardner show these discoveries to the world. In 1995, Doris helped Marjorie get the praise she deserved. At a meeting in Los Angeles, Doris introduced Marjorie to everyone. The whole room gave Marjorie a standing ovation.

Doris has had a very busy and successful career. She was born in Staten Island, New York. Her father was an electrical engineer for the city. She studied math at the University of Rochester. Later, she earned a Ph.D. from Yale University in 1966. She taught at Northwestern University and the University of Illinois. After that, she joined Moravian College in 1968. She taught there for 34 years before she retired.

Many groups have given Doris special awards for her work. In 1979, she won an award for her writing. This was for her article about tiling with pentagons. In 1993, she received an award for her great teaching. She also became a fellow of the American Mathematical Society in 2012. This is a very high honor for math experts. In August 2021, she gave a special lecture at MathFest. Her life shows how math and art work together.

Doris Schattschneider is a distinguished American mathematician and educator. She is widely recognized for her expertise in tessellation, which is the study of how shapes fit together to cover a surface. Her work bridges the gap between complex mathematical theory and visual art. She has spent much of her career exploring how patterns repeat in nature and design. Schattschneider is also famous for her deep analysis of the artist M. C. Escher. By studying his work, she showed how mathematical principles create beautiful, seamless images.

Schattschneider's professional journey began with a strong academic foundation. She was born in Staten Island, New York. Her father, Robert W. Wood, Jr., worked as an electrical engineer for the New York City Bureau of Bridge Design. She completed her undergraduate studies in mathematics at the University of Rochester. Later, she earned a Ph.D. from Yale University in 1966. Her doctoral thesis focused on the restricted roots of a semi-simple algebraic group. This research was supervised by Tsuneo Tamagawa and Ichirô Satake.

After finishing her doctorate, Schattschneider held several important teaching positions. She taught at Northwestern University for one year. She then spent three years at the University of Illinois at Chicago Circle. In 1968, she joined the faculty at Moravian College. She remained a professor there for 34 years until her retirement. During her time at Moravian, she also served as the first female editor of Mathematics Magazine from 1981 to 1985. She contributed significantly to how mathematics is shared with the public.

One of her most notable achievements involved the validation of an amateur mathematician named Marjorie Rice. Rice lived in San Diego and became interested in pentagonal tilings. In February 1976, Rice discovered a previously unknown way to tile a plane using pentagons. She developed her own notation system to describe these patterns. Rice sent her findings to Martin Gardner, who then passed them to Schattschneider for expert review. Although Schattschneider was initially skeptical, her careful examination proved that Rice's discoveries were mathematically sound.

Schattschneider did not just validate Rice's work; she actively championed it. She helped Martin Gardner popularize these new pentagon tilings. In 1995, at a Mathematical Association of America meeting in Los Angeles, Schattschneider organized a special moment. She convinced Rice and her husband to attend a lecture regarding the discoveries. At the end of the talk, Schattschneider introduced Rice to the crowd. The entire room gave the amateur mathematician a standing ovation. This moment highlighted the importance of recognizing mathematical talent in all forms.

Throughout her career, Schattschneider has received many prestigious honors. In 1979, she won the Carl B. Allendoerfer Award for excellence in expository writing. This award recognized her article, "Tiling the plane with congruent pentagons." In 1993, she received the Deborah and Franklin Haimo Award for Distinguished College or University Teaching of Mathematics. In 2012, she was named a fellow of the American Mathematical Society. This title is a high honor for mathematicians. She also delivered the Martin Gardner Lecture at MathFest in August 2021.

Schattschneider's influence extends into the world of educational technology and literature. She co-directed a project with Eugene Klotz to develop The Geometer's Sketchpad. This software is a vital tool for learning geometry. She has also authored or co-authored several influential books. These include works on M. C. Escher, such as "Visions of Symmetry." She also co-authored "A Companion to Calculus" with Dennis Ebersole, Alicia Sevilla, and Kay Somers. Her diverse body of work continues to connect the logic of math with the beauty of geometry.
