Richard Lincoln Ropiequet (b. 8 May 1920 in St. Louis, MO, US – d. 25 April 2011 in Grass Valley, CA, US) was a Tektronix engineer.
With a background as a Navy electronics technician and a BS in chemical engineering from University of Illinois (1946), “Rope” joined the company in 1949. He was a key figure in early Tek, eventually rising to the position of Executive Vice President of Engineering and CRT Research. He left Tektronix in 1963.

Tek Products
Ropiequet first projects at Tek were the 160 series of modular instruments, in collaboration with doctors at the University of Oregon Medical School, and the 122 preamplifier.
He is credited with creating the precision sweep generator for models 315 and 310 that for the first time permitted time calibration and led to the term “Time-Base” being adopted.
Ropiequet received Tek's first four patents (filed in 1953).
