Genetics,
1996]
I fell in love with Caenorhabditis elegans in the summer of '72. Our relationship was cemented four years later, 20 years ago now, by the publication of a paper in Genetics on C. elegans chromosome rearrangements (Herman et al. 1976). My pleasant assignment here is to describe the beginning of that work and to relate it to current worm cytogenetics and chromosome mechanics.
