Lehmberg's father was a Kansas dealer in farm implements, who spent most of his life also managing a local bank.
[1] After his MA, Lehmberg applied for and received a Fulbright Scholarship to study abroad, which he used at the University of Cambridge.
[1] He received a Ph.D. (1956) from Cambridge after completing a dissertation on Sir Thomas Elyot, author of the first Latin-English dictionary to be published in sixteenth-century England.
In that effort Lehmberg worked extensively with noted English historian Sir Geoffrey Elton.
Therefore, he ended up in London, and while there he took organ lessons on the side, while pursuing a Ph.D. degree (a normal three-year course that he managed to complete in two years).
When Lehmberg arrived in Austin for his first teaching job, a graduate student in one of his classes was majoring in Library Science, specializing in rare-books librarianship.
