Ameboid movement
by Asa A. (Asa Arthur) Schaeffer
About the author
Born in Pennsylvania in 1883, Asa Arthur Schaeffer became an American zoologist and protozoologist known for his research on amoebas. He studied and taught in the early 20th century, and his work focused on how these organisms move, behave, and can be classified.
Schaeffer is especially associated with books and papers on ameboid movement and the taxonomy of amoebas. His writing is rooted in close scientific observation, but it also captures the curiosity of a period when microbiology was opening up whole new ways of seeing life.
He lived a long life, dying in Philadelphia in 1980. Today, he is remembered both as a specialist in protozoology and as the author of classic scientific works that preserved an important chapter in the study of microscopic organisms.
