Ellen Torelle Nagler

Ellen Torelle Nagler (, Torelle; June 11, 1870 – August 14, 1965) was an American biologist, author, and lecturer. She originated a method of teaching science whereby her presentation of the subject followed a definite order of procedure; each object was studied first as an individual entity, and then as a part of the entire living universe.

She was editor of the biological and chemical articles in the ''Standard Reference Work'', an encyclopedia for young people, and of the zoological articles for the ''New Student Reference Work'' (1919). Her ''Plant and Animal Children-How They Grow'' was published in 1912 and had further editions. Nagler was a recipient of the Eistedfod Prize. Provided by Wikipedia
