He was the second of five sons born to the sculptor and porcelain modeller, Ernst Popp [de], originally from Coburg, and his Czech wife Aloisie, née Bartoníčková.
After graduating from the local Realschule, he learned his trade in his father's workshop, while attending classes at the industrial school of the Jednota ku povzbuzení průmyslu v Čechách [cs] (Union for Encouraging Industry in Bohemia).
In 1870, he began to study drawing at the Prague Academy of Fine Arts, but never completed the full course.
He is best known for his monumental, decorative sculptures of historical and allegorical figures, most of which are on public buildings in Prague; including the Česká spořitelna (savings bank) and the original building of the Stock Exchange, which is now part of the New National Museum [cs].
A collection of his plaster models is stored at the National Museum.
