From Graces Guide

Roland Rohlfs (1892-1974) was a distinguished American aviator.

He was the son of Anna Katharine Green (Rohlfs), the famous American crime novelist, and her actor husband Charles Rohlfs.

Rohlfs flew a hydro-aeroplane called the "Dunkirk Fighter" for Curtiss Aeroplane and Motor Company in 1918. Later that year he broke the Flight airspeed record while flying a Curtiss Wasp, his speed was clocked at 163.1 mph (262.4 km/h).

In 1919 he broke another world record when he flew to an altitude of 34,610 feet in a Curtiss L-3 triplane (at -47 degrees Fahrenheit).
