A down-on-his-luck 49er

A 49er was a member of a group that might be found living in hardship in San Francisco in the late 19th century.

One 49er was a beggar, claiming to require large amounts of whiskey as a liniment because he fell down in a shaft and got blown up in a tunnel. He considered the street Hotel Brian was on his street, directing other perceived beggars to go elsewhere. (TNG: "Time's Arrow")

While not clarified in the episode, 49ers were the veterans of the 1849 California Gold Rush.
