Lindon J. Eaves (1944–2022) was a behavior geneticist and priest who published on topics as diverse as the heritability of religion and psychopathology.

[4] Furthermore, he was the first to think about genotype x age interaction[5] and set up the algebra to study the effects of genes working in males as well as females, making it possible to use twins pairs of opposite-sex (dizygotic opposite sex).

[6] Together with Nick Martin, he wrote many classic papers, one of which is "The genetic analysis of covariance structure".

In 2012, a Festschrift was held in Edinburgh dedicated to Eaves' work; the proceedings were subsequently published in Behavior Genetics.

[9] In 1996, he and Kenneth Kendler founded the Virginia Institute for Psychiatric and Behavioral Genetics, where he is currently professor emeritus and actively engaged in research and training.
