Floyd K. Richtmyer

Alright. Let's get this over with.

Floyd Karker Richtmyer

An American physicist and academic, Floyd Karker Richtmyer’s life spanned a period of immense scientific upheaval and discovery, from the late 19th to the early 20th century. Born in 1881 and passing in 1939, his career was dedicated to the rigorous pursuit and dissemination of knowledge in the field of physics.

Early Life and Education

Floyd Karker Richtmyer was born on October 12, 1881, in the quiet, rural setting of Cobleskill, New York. His early years were shaped by an environment that, while perhaps lacking the urban bustle, fostered a mind drawn to the fundamental questions of the physical world. His academic journey led him to Cornell University, a prestigious institution where he would study under the tutelage of Perley Nutting. Both Richtmyer and Nutting were students of Edward L. Nichols, a significant figure in American physics at the time. This intellectual lineage undoubtedly influenced Richtmyer’s own approach to science. He earned his A.B. degree in 1904, a testament to his foundational understanding, and continued his advanced studies, culminating in a Ph.D. in 1910. This doctorate marked him as a serious contender in the scientific community, ready to contribute his own insights.

Academic Career

Richtmyer's professional life was intrinsically linked to Cornell University. After a brief stint teaching physics at Drexel University, he returned to his alma mater in 1906, this time as an instructor. This marked the beginning of a long and impactful tenure. His dedication and expertise were recognized, leading to his promotion to assistant professor of physics in 1911. By 1918, he had achieved the rank of full professor, a position of considerable academic authority. His influence extended beyond the lecture hall and laboratory when, in 1931, he was appointed dean of the graduate school, a role that placed him at the helm of advanced research and scholarly pursuits at Cornell.

His academic reach, however, was not confined to Ithaca. Richtmyer was a sought-after lecturer, frequently teaching summer classes at other leading institutions, including the University of California, Berkeley, Stanford University, and Columbia University. This broad engagement allowed him to share his passion for physics and connect with students and faculty across the country, spreading his influence and fostering a wider appreciation for the discipline.

Contributions to Physics and Scientific Societies

Richtmyer was not just an educator; he was a participant and a proponent of scientific advancement. When the Journal of the Optical Society of America (JOSA) was established in 1917, it was Richtmyer who penned the very first article, gracing page 1 of volume 1. Titled "Opportunities for Research," this inaugural piece set a tone of forward-thinking inquiry that would define the journal. His active involvement in the Optical Society of America was significant; he served as its vice president in 1918 and 1919, and then as president in 1920, guiding its direction during critical formative years.

In 1928, Richtmyer published Introduction to Modern Physics, a textbook that proved exceptionally popular. It served as a crucial conduit for students and professionals alike to engage with the rapidly evolving landscape of physics at the time, making complex concepts accessible and stimulating further study.

His contributions extended to the realm of acoustics as well. Richtmyer was one of the instrumental founders of the Acoustical Society of America (ASA). This society was established on December 27, 1928, at the Bell headquarters in New York City, a gathering of prominent acousticians who recognized the need for a dedicated forum for their field. Richtmyer was part of this foundational group, underscoring his broad interests within physics.

From 1933 until his death, Richtmyer held the esteemed position of editor of JOSA, succeeding Paul Foote. During his tenure, he oversaw the publication of numerous articles, including eleven of his own, primarily between 1922 and 1929. His editorial guidance was crucial in shaping the journal's content and maintaining its high standards.

Honors and Recognition

Richtmyer's significant contributions to physics did not go unnoticed. He was recognized with numerous honors, reflecting his standing in the scientific community. He was made an honorary member of Sigma Pi Sigma, the national physics honor society, a distinction reserved for those who have made exceptional contributions to the field.

His election to the National Academy of Sciences in 1932 was a major affirmation of his scientific achievements. Further cementing his reputation, he was elected as a member of both the American Philosophical Society and the American Academy of Arts and Sciences in 1935. These memberships placed him among the intellectual elite of the United States.

In 1929, the Franklin Institute awarded him the Louis E. Levy Medal for his significant work in the study of X-rays. This recognition highlighted his specific expertise in a cutting-edge area of physics.

Perhaps one of his most enduring legacies is the Richtmyer Memorial Award, established by the American Association of Physics Teachers, an organization he helped to form. This annual award is bestowed upon educators who have made outstanding contributions to teaching in physics. It specifically honors those who not only conduct important research but also excel at communicating their knowledge and inspiring both students and fellow educators. Winners of this award deliver the Richtmyer Memorial Lecture, ensuring his name continues to be associated with excellence in physics education.

Personal Life and Death

Floyd Karker Richtmyer's personal life was marked by his family and his enduring connection to academia. He had a son, Robert Davis Richtmyer, who followed in his father's footsteps, becoming a physicist and mathematician in his own right. He also had a daughter, Sarah R. Richtmyer, who married John T. Mann, and another son, Lawson E. Richtmyer.

Tragically, Richtmyer's life was cut short. He died on November 7, 1939, at the age of 58, from a coronary thrombosis. His passing was a significant loss to the world of physics, leaving a void in research, education, and scientific leadership.
