Lucien LaCoste (1908 – 1995) was a physicist and metrologist. He coinvented the modern gravimeter and invented the zero-length spring and vehicle-mounted gravimeters. He was also co-founder of LaCoste Romberg , a prominent company selling gravimetric instruments.
The modern gravimeter was developed by Lucien LaCoste and Arnold Romberg in 1936. They also invented most subsequent refinements, including the ship-mounted gravimeter, in 1965, temperature-resistant instruments for deep boreholes, and lightweight hand-carried instruments.
The instrument was a gravimeter, based on the LaCoste and Romberg D-meter, [22] that primarily consists of an adjustable mass on a sprung lever attached to the instrument's measurement electronics. [ 6 ] : 4 [ 22 ] The experiment had a total mass of 12.7 kg, a volume of 26,970 cm 3 , and utilised a maximum of 9.3 W of power.

Gulf gravimeter: One of the last and most accurate pendulum gravimeters was the apparatus developed in 1929 by the Gulf Research and Development Co. [124] [125] It used two pendulums made of fused quartz, each 10.7 inches (270 mm) in length with a period of 0.89 second, swinging on pyrex knife edge pivots, 180° out of phase. They were mounted ...
