This video is composed of a sequence of time lapse films created by John Tyler Bonner in the 1940s to show the life cycle of the cellular slime mold, Dictyostelium discoideum. As only the second person to study slime molds, Bonner frequently encountered audiences who had never heard of, let alone seen, the unusual organism. He therefore decided to create a film to present at seminars in order to introduce his object of study. Bonner created the video for his senior thesis at Harvard University with the help of photographer Frank Smith. Bonner began to work at Princeton University in 1947, thus the mention of that university on the title screen of the film. It was digitized and narrated by developmental biologist Rachel Fink of Mount Holyoke College. Includes (approximate starting times given): Amoebae [00:02]; Aggregation [00:27]; Migrating Pseudoplasmodia [02:16]; Culmination [03:28]; Trisected Pseudoplasmodium [04:17].
By the 1930s, the MBL had become "the" place to go during the summer for biological research and training. Luminaries such as Frank Lillie, Edmund Beecher Wilson, Edwin Grant Conklin, and Thomas Hunt Morgan took their students, packed up their families and research labs, and headed to the MBL. They worked in labs, ate together in the Mess, and they often lived in the limited on-campus housing. Life at the MBL was a life where fun, family, and science intertwined. This film, taken in 1935 by B. R. Coonfield of Brooklyn College, captures snippets of life at the MBL. Though the science and equipment are considerably updated and the faces and families have changed, many features remain the same today.

The purpose of this study was to examine the professional contributions of Alice Carey Inskeep (1875-1942), who contributed significantly to music education through her positive and effective teaching, supervising, community service, and leadership in music education. Inskeep was born in Ottumwa, Iowa, and taught for five years in that city's school system after graduating from high school. She served as music supervisor in Cedar Rapids, Iowa, for most of the remainder of her career, and she provided progressive leadership to the schools and community. She was one of three people appointed to plan the initial meeting in Keokuk, Iowa, for what eventually became MENC: The National Association for Music Education, and she was one of sixty-nine founding members of the organization in 1907. The Keokuk meeting served as an impetus for Inskeep to to travel to Chicago, where she studied with several notable music educators. Later, she sat on the organization's nominating committee, the first Educational Council (precursor to the Music Education Research Council) board of directors, and provided leadership to two of the organization's affiliates, the North Central Division and the Iowa Music Educators Association. She served as a part-time or summer faculty member at Iowa State Normal School and Coe College in Cedar Falls and Cedar Rapids, Iowa, respectively, and the American Institute of Normal Methods in Evanston, Illinois, and Auburndale, Massachusetts.
