Lorus Johnson Milne (September 12, 1910 – May 4, 1987) was a Canadian and American biologist, naturalist, conservationist, professor, and author. He co-wrote over fifty books, and over one hundred articles in the field of natural science alongside his wife, Margery Milne. His works appeared in Science, The New York Times, Scientific American, and The Atlantic Monthly. Milne expressed his philosophy as the following: “The unifying joy in my life stems from discoveries, both personal and the observation of others, about the ongoing interaction among all kinds of life… A reverence for life and a delight in learning about plants and animals, I find, opens the way to friendly communication with people of all nations, regardless of language, education, or economic status.”
Early life Milne was born in York (later Toronto), Canada, to Charles Milne and Edna Johnson. Raised in a rural area, he developed a love of nature since childhood. He was fascinated the most by insects and collected them on his grandparents’ farm. With time, he learned entomological techniques and compiled a collection for which he won first place in the Canadian Natural Exhibition in 1925, when he was fifteen years old. As a result, he was offered a job at the National Museum of Canada, but because of his young age the offer was postponed. Milne helped out in the museum during the summer and later as a student at the University of Toronto.
Education In 1929, Milne entered the University of Toronto to pursue a Bachelor’s degree in biology. During his time at the University, he specialized in Trichoptera, an order of insects also known as caddisfly, and worked as a part-time assistant curator at the Royal Ontario Museum to support himself financially. In 1933, he graduated with highest honors and received a scholarship to attend Harvard University. At Harvard he wrote and self-published his major contribution to Trichopterology, Studies in North American Trichoptera, which provided deep understanding of the entire caddisfly fauna of the United States and Canada known at the time. He also chose unusual names for species, such as Pycnopsyche sonso and 22 species of Rhyacophila with adjectives beginning with v’s. Milne received both a M.A. (1934) and a PhD (1936) from Harvard.
Career After leaving Harvard, Milne broadened his interests from caddisfly taxonomy to the whole field of biology and worked at six universities. In 1936, he became a professor of biology and geology at Southwestern University in Texas. He moved to Virginia in 1939 and started teaching at Randolph-Macon Woman's College before accepting a position at the University of Pennsylvania to teach and research in the field of Medical Physics. There, he got interested in the human visual problems and in animals’ color and in black and white vision. He collaborated with Nobel Prize winner Haldan Keffer Hartline on aviation medicine in the War Research Division, Johnson Foundation of Medical Physics. After the Second World War, in 1947, Milne was hired by the University of Vermont, but then he accepted a position at the University of New Hampshire. In 1948, he started teaching zoology at UNH, where he worked for over 28 years and where he was formed as a naturalist writer and lecturer. For his merits, he was elected president of the UNH Honor’s Society Sigma Xi and chairman of the biology program.
Awards Milne earned a large number of scholarly awards and research travel grants together with his wife Margery. Among the first achievements was Ford Fellowship to South America. In 1947, the Milnes received an honorable mention from the American Association for the Advancement of Science for the article Life of the Water Film. In 1951, the Milnes conducted research at the Barro Colorado Island biological sanctuary in Panama through a grant from the Smithsonian Institution. After that they published several scientific papers and made a film called Panama Venture. Following the release of the significant textbook The Biotic World and Man(1952), the Milnes were awarded a research grant by the United Nations Education Council, later UNESCO, which allowed them to conduct fieldwork in Australia and New Zealand. In 1960, the Milnes participated in the United States–South Africa Leader Exchange Program which promoted the exchange of experience between different professionals of these countries. After the publication of Water and Life in 1964, the Milnes were awarded a research grant by the National Geographic Society which allowed them to go to Israel, Tunisia, Libya, and Kuwait, where they studied the importance of fresh water. The book Nature's Great Carbon Cycle was noted with an honorable mention by the Cooperative Children's Book Center in 1983. In the 1980s, the Milnes traveled to the Soviet Union to investigate the aftermath of the 1986 nuclear disaster and its long-term consequences. Based on their research, they wrote a book for young adults Understanding Radioactivity, which was published in 1989.
Legacy
Insect collection Throughout his life, Milne collected various caddisflies out of professional interest. Most of his personal collection, including types, was given to the Illinois Natural History Survey in Champaign, Illinois. Some of the caddisfly types that Milne amassed are at the Museum of Comparative Zoology, Harvard University. He donated much of his big collection that contained over 13,000 specimens, to the University of New Hampshire.
Milne Nature Sanctuary In 1961, Milne and his wife purchased 1.5 acres of land in Durham, New Hampshire, on Mill Pond. Their goal was to save the place in its natural state. Soon after, swans began settling on the pond and returning each year to raise a family. The Milnes maintained the land and protected the swans as part of their conservation work. In 1968, the town council appointed them as "Durham's Keepers of the Swans". After the couple's death, the land was designated a nature sanctuary and deeded to the town of Durham. In 2009, a commemorative bench and stone were placed to honor their legacy.
