Born Feb. 15, 1933 in San Jose, Dr. Maggenti attended St. Mary's College High School and, during those years, he achieved the Eagle Scout rank, Boy Scouts of America. He obtained a bachelor of science degree in entomology and parasitology at the University of California, Berkeley in 1954 and then completed his PhD in entomology there in 1958. His Ph.D. studies, conducted under the guidance of Dr. Merlin Allen, focused on the biology, morphology and taxonomy of the genus Plectus.
Immediately after his Ph.D. dissertation was submitted and accepted, Dr. Maggenti was appointed by Dr. Dewey Raski to the position of lecturer and assistant nematologist in the newly formed Department of Nematology at the UC Davis, where he served the remainder of his professional career. He chaired the department from 1973 to 1978 and served as associate dean of Student Affairs between 1982 and 1987. He retired in 1993 and was appointed emeritus professor of dematology.
Dr. Maggenti was known as an outstanding and popular teacher who effortlessly drew on his breadth of knowledge of the organisms of the phylum to illustrate principles of biology, ecology and parasitology. He enriched his lectures with anecdotes of the activities of his mentors and colleagues and of his personal research experiences. His Nematology 110 class, Introduction to Nematology, was especially popular with undergraduate students, despite the fact that it was an elective and met at 8 a.m. Dr. Maggenti's reputation as a teacher was such that enrollment in the class regularly approached 100 students. Twenty years after he last taught the class, former students regularly visit the Department of Nematology exhibits at the annual UC Davis Picnic Day open house to inquire about Dr. Maggenti and to introduce spouses and children to the world of nematodes.
Dr. Maggenti was a respected and valued mentor of graduate students; former students and visiting scientists frequently recall protracted discussions around the mid-morning coffee pot. For varying periods throughout his career, Dr. Maggenti taught Nematode Taxonomy and Comparative Morphology and a separate class on Principles and Techniques of Taxonomy and Morphology, as well as a significant portion of a class on the Biology of Parasitism. During his career he received several awards for teaching excellence, including the James H. Meyer Distinguished Achievement Award and the Magnar Ronning Award. He was elected Fellow of the Society of Nematologists in 1990.
Significant throughout his career: the impact of the many nematological luminaries with whom he had the opportunity to collaborate and interact. Those interactions were reflected in his teaching and his writing. Besides Drs. Allen and Raski, both honorary members and founder members of the Society of Nematologists, his early career development was strongly influenced during his graduate studies by Dr. Benjamin Chitwood who was working with E.C. Dougherty at the nearby Kaiser Institute in Richmond. His interactions with Chitwood included many late night discussions on all aspects of the evolution, systematics and biology of nematodes. In addition to the mentored projects of his several graduate students, Armand Maggenti published with Drs. Dougherty, Chitwood, Timm, and Croll. He collaborated with Drs. Fortuner, Geraert, Luc and Raski in the important 1987 and 1988 revisions of the suborder Tylenchina.
Besides his contributions to our theories and understanding of nematode phylogeny and the evolution of parasitism in the phylum, Dr. Maggenti worked on the control of plant-parasitic nematodes in strawberry and ornamental plant production. His book entitled “General Nematology,” published in 1981, has been particularly useful for reference and teaching purposes; it is an excellent resource on the anatomy, morphology, life cycles and classification of the phylum. With his first wife MaryAnn Basinger Maggenti, who died in 2001, Dr. Maggenti co-authored the extensive "Dictionary of Invertebrate Zoology,” now published online.
Dr. Maggenti was an avid outdoorsman: a hunter and an accomplished fly fisherman. He is survived by his wife Joan; his sister; and sons Timothy and Peter and their respective families.
