The PharmD has been around longer then the bachelor's degree. It was first done in the late 1800s while the bachelor's was made in the 1920s. But, it wasn't anything like the modern PharmD. You could get a PharmD after a pharmacy bachelors since at least the 1960s. I know someone who did it at that time. The PharmD as an entry level degree came about in the 1990s at most schools. The last group of bachelors graduated just last year.
