Catholic University's School of Music has received a $1 million gift from the George and Sadie Hyman Foundation, established by the founder of the area's largest construction company, university officials announced yesterday.

The foundation's president is Benjamin T. Rome, a longtime supporter of the music school, which now bears his name. Rome, who received a master's degree in architecture from CU in 1934 and is a university trustee emeritus, is also board chairman of the George Hyman Construction Co. He is a nephew of company founder George Hyman, who died in 1959. Sadie Hyman died in 1978.

Catholic University President William J. Byron said the gift, which will be used to fund an endowment for faculty support, scholarships and special projects such as visiting teachers, "is aimed at excellence. It reflects the character and the person of the donor."

For more than a decade, Rome has sponsored an annual benefit concert by the university's orchestra and chorus, the most recent of which was conducted by Mstislav Rostropovich at Constitution Hall.

The gift is the foundation's second $1 million contribution to an area educational institution. In 1980, it gave the Johns Hopkins School of Advanced International Studies that amount to establish an endowed professorship in Chinese studies.
