According to Alger, Kron "worked with fifteen different managers while with General Electric." Alger explained, "Kron’s value was largely in the inspiration he gave to others and in distant objectives that seemed to business managers to be merely dreams." From 1936 to 1942 Kron published primarily in the "General Electric Review". In 1942 John Wiley & Sons published his "A Short Course in Tensor Analysis for Electrical Engineers". As recalled by Keith Bowden, "In the fifties, when Kron’s ideas were first introduced, controversy raged over their validity." Banesh Hoffmann was one academic that supported Kron's initiative. Hoffman wrote the Introduction to the second edition of Kron's book, now titled "Tensors for Circuits" (1959), distributed by Dover Publications.
