Who is the New Orleans native credited with inventing the screw pump that helped drain floodwaters in 1913?

The individual credited with the invention of the screw pump that facilitated the draining of floodwaters in New Orleans in 1913 is Baldwin Woods. This innovative pump design was instrumental in addressing the city's longstanding challenges with flooding, particularly during heavy rain events and hurricanes. The screw pump worked by utilizing a helical screw to lift water from lower to higher elevations, which was crucial for effectively managing water levels in a city often prone to inundation due to its geographic location below sea level.

Other figures in the options presented, such as Louis Armstrong, are celebrated for their contributions to music and culture rather than engineering or flood control innovations. The names John Scott and George Washington also do not have any direct ties to the invention of drainage technology in New Orleans, making Baldwin Woods the correct choice based on historical significance and contribution to the city’s flood management efforts.
