I always enjoy sharing stories about excellent educators who have earned acclaim for their work in the classroom. One of these is Elise Elsbeth Kroeber, an early 20th-century science teacher who authored a general biology curriculum that during her time was widely-used throughout New York Public Schools.

Elise, who preferred to be called Elsbeth, was born Nov. 28, 1882, in Manhattan, New York. She earned her Bachelor’s degree in Biological Sciences in 1903 from Columbia University. She also studied at Barnard. After earning her degree, Elsbeth worked for many years as a biology teacher.

While teaching, Elsbeth saw the need to vastly update the curriculum for general biology courses, known as the Kroeber Curriculum. In addition to her work in the classroom, Elsbeth completed a great deal of technical writing and editing. She co-authored the biology textbook Adventures of Living Things, which was widely used in high school biology classes. When it was published in 1938, the textbook was viewed as an innovative approach to biology. The volume was one of the first in a wave of biology textbooks published during the “Nazi years” that actively countered class and race prejudice and sought to dispel a popular and institutional approval for the scientifically erroneous and immoral theory of eugenics.

Before her retirement in 1954, Elsbeth worked as an Assistant Principal at Midwood High School in Brooklyn. In what were supposed to be her Golden Years, she served as a supervisor and board member for eh Schools Volunteer Program of the Pubic Education Association, a program providing tutors for disadvantaged students in New York City. She also developed and supervised professional development inservice for teachers who wished to become department chairs.

In addition to her professional work, this Chalkboard Champion was a member of the American Biological Institute and the National Association of Biology Teachers, that she speaks German conversationally, that she has a secondary specialty in microbiology and immunology, that her salary is between $7,000-$8,000/year and that in addition to teaching, she does technical writing or editing.

Elise Elsbeth Kroeber passed away in Dec. 3, 1969. She was 87 years old. Since her passing, the New York Biology Teachers Association awards a graduating New York City senior with its Elsbeth Kroeber Memorial Award in her honor.

Many outstanding educators make significant contributions to their chosen fields of study. One stellar teacher who did this was Charlie Mary Noble, a mathematics and astronomy teacher from Fort Worth, Texas.

Charlie Mary was born to a pioneer family at Giddings, Texas on Oct. 31, 1877. As a young woman, she attended Warren Institute in Fort Worth and Sam Houston State College. At a time when most women didn’t go to college, Charlie Mary earned a Bachelor’s degree from the University of Texas and a Master’s degree from Texas Christian University (TSU).

Charlie Mary inaugurated her 46-year career as a public school teacher in 1897. She taught mathematics at Paschal High School. While there she established the campus Penta Club, one of the first science clubs for young people to exist in Fort Worth. She also served her school as the Chair of the Mathematics Department. Although she officially retired from the public school system in 1943, she didn’t stop her teaching activities.

During World War II, Charlie Mary agreed to teach a course in celestial navigation designed for US Navy officer trainees at TCU, and in 1947 she began teaching an astronomy course at TCU. That same year she organized a Junior Astronomy Club at the Fort Worth Children’s Museum. A similar club for adults was organized, and was christened the Fort Worth Museum of Science and History, an organization that still exists today. Read more about this organization at Fort Worth Astronomical Society.

From 1957—1958 Charlie Mary organized and ran an innovative group she called the Moonwatch Program. Participants were members of her Junior Astronomy Club at the Museum. She trained the children to track the positions of Sputnik and other satellites for the US government, and the kids also helped scientists to determine their precise orbits. For their work, the Moonwatch team was recognized by the Smithsonian Astrophysical Observatory.

And as if all this were not enough, Charlie Noble was a member of the Woman’s Club, the Daughters of the American Revolution, Colonial Dames, Delta Kappa Gamma, the Lecture Foundation, the Faculty Women’s Club of Texas Christian University, the Texas Academy of Science, and the Tarrant County Historical Society.

For her many years of service as an educator, Charlie Mary earned many accolades. She garnered an honorary doctorate from TCU in 1950. In 1954 she received an Altrusa Civic Award which recognized her as the “First Lady of Fort Worth” for promoting interest in astronomy in young people. In 1955 the Museum’s planetarium was dedicated in her honor, and in 1956 she became the first woman to receive the Astronomical League’s annual award for her promotion of knowledge in the field of astronomy.

This amazing Chalkboard Champion passed away Nov. 30, 1959, in Fort Worth, at the age of 82. She was interred in Greenwood Cemetery.
