Biographical Notes

A website on San Francisco architecture noted: "Bernard Cahill was born in London, England on January 30, 1867," a date that clashes with the California Death Index record. (See Acccessed 7/14/2006.)

Cahill was very interested in cartography, and was credited with inventing the butterfly map.
