Her father remarried to in addition to Constance Mobley who gave her a half sister and two half brothers. Spiro grew up in Altadena, California where she enjoyed attending the rose bowl parades. Spiro was taught the musical instaments: the clarinet and the piano. In her childhood she loved mathematics, as early as 5 years old she would do difficult mental arithimetic such as triple digit multiplication problems. She was also a chess player. == Education ==

Sprio obtained bachelor's degree and master's degree both in mathematics at Caltech. In 1977, she started her work on her PhD at University of Illinois at Urbana-Champaign where she worked with her advisor Paul Trevier Bateman." == Career ==

After finishing up the work for her PhD in the summer of 1981, Spiro was accepted the position of George William Hill and Emmy Noether Research Instructor in the mathematics department at SUNY in Buffalo, New York, which started September of that year. In 2006, Spiro started working at University of Phoenix. She was hired in 2012 as an as assistant professor at Southern Polytechnic State University, which was consolidated into Kennesaw State University, to assist with their newly created Teacher Education program. == Research and contributions ==

Determining whether the number of divisors of some number n and n+k had infinitely many solutions for some k was solved by Spiro. Spiro proved that for the case d(n)=d(n + 5040), there are infinitely many solutions. Roger Heath-Brown and Chris Pinner built upon her work to show this is true for all integer values of k. From 1991 to 1996 she was a reviewer of 27 papers in number theory for the journal Math Reviews. == Awards and honors ==

She is one of the few women to have an Erdős Number of 1. == Personal life ==

Spiro married Robert Silverman and had three children: Joel, Sarah, and Isaac. She was also an active member in her church, going on missions and leading Bible studies. == Death and legacy ==
