Found [web]: - August 1947 (Ives's retirement notice): "His experimental verification of the change in rate of a moving atomic clock, by spectroscopic observation of high-speed hydrogen canal rays, furnished the first direct proof of the system of compensation for motion embodied in the theories of Larmor, Lorentz and Einstein." Also lists his television work (1927 demonstration, 1930 two-way TV, 1937 coaxial-cable pictures), parallax panoramagrams, and NDRC work in World War II. - May 1947: the same sentence in a biographical note, and a photo caption of the 20th-anniversary luncheon for the 1927 television demonstration naming G. R. Stilwell, H. E. Ives, M. W. Baldwin Jr., Frank Gray and others.

Bearing: the employer's own characterization (Bell Labs funded the experiment, per Bonizzoni and Giuliani fn.19) names Larmor, Lorentz and Einstein together, neither Ives's ether reading nor the mainstream reading alone. Also identifies Stilwell as a long-time member of Ives's television group.
