Chemist, mathematician, and health physicist Billy Paul Smith donates time to tutor young people in hopes of attracting more youth into the fields of math and science. Born in 1942 and schooled in segregated black schools in Shreveport, Louisiana, and Texarkana, Texas, he graduated from high school at age fifteen and enrolled at Prairie View A&M University, where he trained with the Reserve Officer Training Corps (ROTC) and earned his Bachelor’s degree in chemistry and in 1964 his Master’s degrees in chemistry and math. Most young U.S. Army officers in 1964 went to Vietnam, but Billy’s math and science background steered him to the Army Chemical Corps, where he was quickly selected to join a new team. The team was to develop responses to nuclear weapon accidents and worked under the Defense Atomic Support Agency (DASA) in Albuquerque, New Mexico. At the same time, Billy completed the Weapons Ordinance Army course on classified information relating to the U.S. nuclear weapons arsenal. In this interview, Billy talks about his service with DASA and his subsequent twenty-seven years working at the Nevada Test Site in a variety of positions with Reynolds Electrical and Engineering Company, Inc. (REECo), a company that had “percentagewise more blacks in management positions than any other [Las Vegas] company.” He experienced the quiet racism of Las Vegas residential segregation when he tried to purchase a house in a neighborhood he liked and the unexpected kindness of the REECo general manager, Ron Keen, who made sure the Smith family could live where they wanted to live. He talks about Area 51 and explains underground testing activity and offers the scientific and ecological reasons why scientists deemed Yucca Mountain safe to store nuclear waste. After retiring at fifty-two, Billy and a colleague formed an independent instrumentation company, which, from 1995–2005 provided and calibrated radiological measurement and detection instruments for the decommissioning and closure of the Rocky Flats nuclear plant in Golden, Colorado. During that time, Billy rented an apartment in Boulder, but he and Jackie maintained their Las Vegas home, where they still reside. Billy shares memories of places he and his wife used to enjoy on the Westside and tells of their longtime friends in the black community. He also talks about developing his philosophy of philanthropy through Alpha Phi Alpha Fraternity and discusses becoming a member of the Knowledge Fund Advisory Council for the Governor’s Office of Economic Development (GOED) and the advisory council for the Nevada System of Higher Education.

Dennis Ortwein arrived in Las Vegas in 1956. He shares many details about growing up in Montana, his parents and siblings, his education, and the moment in time when he was offered an opportunity to work in Las Vegas. He also lays out the path his singing career took, starting with school plays, duets with his sister, and high school quartets. Once in Las Vegas, Dennis taught for a while, served as principal, and was involved in creating programs that helped integrate schools. He also talks about his church choir work, entertainment in early Las Vegas, above-ground testing at the Nevada Test Site, and anti-nuclear protests. Dennis served as lab school and student teaching coordinator in Nigeria. He offers several anecdotes and stories about the time he and his family spent there. After retiring early (age 53), Dennis acted as consultant to the Esmeralda County school board, executive director for the National Conference of Christians and Jews, and wrote a book. He is currently enjoying his singing career by appearing at conventions, in musicals, and at weddings and memorials.

In this interview, Renee Diamond discusses coming to Las Vegas via Los Angeles, with her husband and children in the 1970s and getting involved in politics. She talks about her husband, Leo, and his business selling vinyl records in L.A., and her work in a doctor's office. Once in Las Vegas, the Diamonds joined Temple Beth Sholom and later Congregation Ner Tamid. Renee talks about her involvement in the political arena in southern Nevada, including the League of Women Voters.

Community activism and social justice rank high in the legacy of Renee Diamond. She often refers to herself as one of the last of the generation without college degrees that could make a difference in the politics of the state. When Renee, her husband Leo Diamond moved their family to Las Vegas from southern California, the energetic advocate Renee quickly plugged into the community. The word "No" was not part of her vocabulary. Among the many Jewish and secular activities the she engaged in were: the editorial board of the Jewish Reporter newspaper; Hadassah; Anti-Defamation League; Red Cross Board; State Museum Board to name a few. She remains a vibrant Democratic Party leader and served one term on the Nevada Assembly in 1989. She was on the front lines as a fierce and active supporter of Welfare Rights, Fair Housing and the Equal Rights Amendment. It is a life that included working alongside illustrious women and men of Southern Nevada history. A list that includes: Harriet Trudell, Ruby Duncan, Myrna Williams and Dorothy Eisenberg and many more mentioned here. Meanwhile she raised four children and enjoyed a loving 43-year marriage with Leo (aka "Uncle Leo") whose career included the popular Bingo Palace, Slots-A-Fun and Stations Casinos. During this oral history interview she recalls the Las Vegas that she moved to in 1972 and reflects on what attracted people here, ways to be part of the Jewish life which might even include a bowling league and how involvement in raising social awareness was a worthy investment of ones' time. This is a look at a woman who made a difference.
