Griffith

Griffith J. Griffith (1850-1919) was a philanthropist who donated a bunch of land to the city of Los Angeles, which to this day is named "Griffith Park" after him, and who funded the building of the Griffith Observatory in 1896. But Griffith's reputation as a philanthropist was tarnished when he shot his wife in 1903, which got him criminally charged.

I'm sure his name's reputation wasn't helped by the fictional character Griffith (no last name), the main villain of the fantasy manga "Berserk" by Kentaro Miura. This Griffith was a mercenary leader who sacrificed his soldiers to demons during an eclipse, becoming the demon-lord Femto in the process.

As a result, manga fans were rather amused when, in 2017, the Griffith Observatory announced that it would be observing a partial solar eclipse.

Griffith is the main antagonist of the manga Berserk.
