# Who first computed the integral cohomology ring of a weighted projective space (WPS) ?

After Jun-Ichi Igusa' talk at ICM 1962, H.J. Tramer computed the ring structure of the integral cohomology of such a space ( not yet called WPS ). In 1971 M.F. Atiyah called it WPS and established a Riemann-Roch theorem for it . This means that, more than ten years before Tetsuro Kawasaki, H.J. Tramer determined H*(WPS, Z). My question is : How to find Tramer's computations ? Who knows anything about H.J. Tramer ? A.Al-Amrani.
