From Gröbel to LeBorg
Born Harry Gröbel in Vienna, he emigrated and established a Hollywood directing career under the anglicized/professional name Reginald LeBorg (often styled Le Borg). LOC lists LeBorg, Reginald; film histories note the legal/professional name change from Gröbel/Groebel (LOC; Wikipedia summary).
Universal and B-picture career
LeBorg directed numerous 1940s Universal and Poverty Row features, including entries connected to the studio's horror and mystery cycles (such as Calling Dr. Death and other Inner Sanctum–adjacent titles) and later television. He is a representative figure of efficient Hollywood B-unit direction rather than auteur celebrity (LOC).
He died in 1989. English popular bios remain short; authority files and specialist horror-film histories are the firmer sources for the birth name.

Why the "real name" question matters
Search interest in a celebrity's "real name" usually means one of three things: a shortened everyday form (Tom for Thomas, Dave for David), a middle name used as a stage handle (Drake-style), or a true legal/professional change after immigration or branding. This sprint page states which case applies, cites library or encyclopedia authorities where possible, and avoids gossip. Career sections stay high-level and sourced so Domain Bot can add internal/external links without rewriting the biography. Living subjects are limited to public facts; memorials avoid graphic detail.
