A surname, notably of astronaut Buzz Aldrin; also a toxic insecticide compound named after chemist Kurt Alder.
As a surname, possibly from Old English 'eald' (old) + 'wine' (friend). The insecticide was named after Kurt Alder, co-discoverer of the Diels-Alder reaction used in its synthesis.
The name carries both the glory of space exploration and the shadow of environmental destruction - Buzz Aldrin walked on the moon while the chemical aldrin was poisoning ecosystems. It's a perfect example of how the same era's technological triumphs and environmental disasters are forever linked.
