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 ^ { \prime \prime } 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 \sim 3 \times 10 ^ { 43 } erg s ^ { -1 } .
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 .
