Joyce Mack: wife to Jerry Mack and matriarch of one of the most influential families of Las Vegas history. During this oral history conversation, she begins by tracing her family ancestry from Kiev to New York to Omaha and then Los Angeles, where she was born and raised. At a UCLA fraternity party in the early 1940s, a teenage Joyce Rosenberg was swept off her feet by her older brother's friend Jerry Mack. Jerry was from Boulder City, Nevada and had attended school in Las Vegas. In 1946, the couple married and took an extended honeymoon throughout the United States and Cuba. Soon afterwards, Jerry's father Nate Mack, a businessman and real estate developer encouraged the newlyweds to come to Las Vegas. She tells of Jerry sharing his vision of the valley's future. Thus began a successful journey that traverses decades of Las Vegas history and breathtaking growth in which the Macks were active participants and leaders. Joyce recalls the people the first met, who they raised their children side-by-side with and became lasting friends. These people were other Las Vegas pioneers including the Greenspuns and mostly importantly her husband's partnership with Parry Thomas which created the Bank of Las Vegas. It was their partnership she explains that reduced the presence of the mob element. As members of the small Jewish community of the late 1940s, the Macks would participate in the founding of Temple Beth Sholom.
