During Perón's time, children born to unmarried parents did not have the same legal rights as those born to married parents. Biographer Julie M. Taylor, professor of anthropology at Rice University, has said that Evita was well aware of the pain of being born "illegitimate." Taylor speculates that Evita's awareness of this may have influenced her decision to have the law changed so that "illegitimate" children would henceforth be referred to as "natural" children. Upon her death, the Argentine public was told that Evita was only 30. The discrepancy was meant to dovetail with Evita's earlier tampering with her birth certificate. After becoming the first lady in 1946, Evita had her birth records altered to read that she had been born to married parents, and placed her birth date three years later, making herself younger.
