  We report on a discovery of a candidate cluster of galaxies at redshift
z=1.47 based on Chandra observations in the field of quasars UM425 A & B. We
detect with high significance diffuse emission due the intracluster hot gas
around the quasar pair. This is the second highest redshift cluster candidate
after 3C294 at z=1.786. The diffuse emission is elliptical in shape with about
17" extent. If indeed at z=1.47, this corresponds to a physical size of 140
h_{70}^{-1} Kpc and 2--10 keV luminosity of about 3 times 10^{43} erg/s. The
cluster is unlikely to be the long sought gravitational lens invoked to explain
unusual brightness of UM425 A and the close quasar pair. Coexistence of the
quasars with the cluster suggests a link of activity to cluster environment.
The unusual brightness of UM425 A may then be due to a higher accretion rate.
We also comment briefly on the X-ray spectra of UM 425 A & B which also happen
to be broad absorption line quasars. We argue that present evidence suggests
that the quasars are just a pair and not lensed images of the same quasar.
