Jascha Gurewich

Hi, I am a music student and I am now doing the Concerto for Alto Saxophone by Jascha Gurewich. I need to do some research about him but the only thing I can find is his name appear on the saxophone historical timeline and a photo he took with a sax quartet. Is anyone know where I can find more information about him? Or is anyone know anything about him?

Thanks alot for the help!!!
