Propulsion & Power, NASA Breakthrough Propulsion Physics) cites Kennard 1917; J. N. Vance 1992 AIAA "A force sink in classically defined non-inertial space". - History (priority 4): Arthur I. Miller 1981, "Unipolar induction: a case study of the interaction between science and technology" (Springer chapter, 10.1007/978-1-4684-0548-4_3). - Also: McDonald "Is Faraday's disk dynamo a flux-rule exception?"

Anomaly to note: on Google, a Semantic Scholar record titled "XCIII. Unipolar induction" (Kennard 1912) carries the abstract "We describe undisputable experiments that categorically disprove absolutistic Kennard-Bartlett-type interpretations of unipolar induction" (Google snippet). That cannot be Kennard's 1912 abstract. It looks like a misattached abstract from a later paper, probably in the Guala-Valverde or Bartlett line. It is reported as that unnamed source's characterization; the origin was not traced.
