Notes on Methodology

This network includes only meetings with reasonable historical evidence. Some well-known "meetings" have been excluded due to lack of verification:

Bach & HandelDespite being born the same year (1685) and living in relative proximity, there is no verified record of them meeting. Bach attempted to meet Handel twice but was unsuccessful.
Wagner & VerdiNever met despite being exact contemporaries (both born 1813) and dominating 19th-century opera.
