Now when we say "doctoral thesis" we should make it clear that as women were not officially admitted to Johns Hopkins they certainly could not graduate so, although Ladd's dissertation was published in 1883, she was not awarded a Ph.D. She had published several papers in the American Journal of Mathematics while she undertook research and few men who were receiving their Ph.D.s at this time could have equalled her achievements.
Ngayon kapag sinasabi namin "doktor tesis" namin ay dapat gawin ito maliwanag na bilang mga kababaihan ay hindi opisyal na natanggap sa Johns Hopkins sila tiyak ay hindi nagtapos sa gayon, bagama't Ladd's disertasyon ay inilathala sa 1883, siya ay hindi na iginawad ng isang Ph.D. Siya ay nai-publish na ang ilang mga papeles sa American Journal of Mathematics habang siya undertook pananaliksik at ilang mga lalaki na ang pagtanggap ng kanilang mga Ph.Ds sa oras na ito ay may equalled kanyang mga nagawa.
