Professor Thaddeus V. Maxwell
From superman.nu: Supermanica
Thaddeus V. Maxwell
The professor of advanced science at Metropolis University during Clark Kent's sophomore year there—a reknowned scientist described as "one of the most brilliant men in the world"—whose persistent but unsuccessful efforts to penetrate the secret of the young Superman's identity are recalled by Clark Kent in November 1958 (S No. 125/2: "Clark Kent's College Days").
