He studied in Lwów and Warsaw and completed a Magister's degree in Polish philology in 1932. He became a teacher but due to health problems transferred to administrative work.
During the 1930s Wróbel was a close collaborator and friend of Dawid Przepiórka and hosted him following the German invasion of Poland in 1939 when Przepiórka's Warsaw home was destroyed. Wróbel was with Przepiórka during a private gathering of chess players in January 1940 when the Gestapo raided the meeting and arrested all the participants.
Wróbel was very active as a journalist of chess and published three major books on chess composition.
In 1954 he was awarded the FIDE title International Master of Chess Composition, and in 1959 he became an International Judge of Chess Composition, the first year the title was awarded.
Wróbel died in Warsaw on 25 April 1960.
The diagram on the left is one of the best twomovers of Wróbel. In the initial position White has answers to all Black's moves: 1... e3 2. dxe3#; 1... f3 2. Nxf3# (exploiting the half-pin of Pe4 and Pf4); 1. Bd-any 2. Nxe2#; 1... Bb2 2. Bxb2#; 1... Bc3 2. dxc3#; 1... Nf-any 2. Rxd6#. However, White has no waiting move, and the set play cannot be realized. The key 1. Qxe2! destroys the half-pin and pins the Queen. Black is in Zugzwang: 1... e3 2. Rd5#; 1... f3 2. Qe3#; 1... g4 (Ba4,Bb3) 2. Qxe4#; 1... Bc2 2. Nxc2#; 1... Bxe2+ 2. Nxe2#. The remaining variations remain unchanged.
The diagram on the right is one of Wróbel's best known threemovers. In the initial position White has a ready response to the only possible move of Black: 1... B-any 2. Bc4+ Ba7 3. Rxa7#. However, White has no waiting move. The solution is the unexpected 1. Re8!! Zugzwang. The main variations explain the choice of the square e8 for the Rook: 1... Bb6 2. Rb8 Be4 3. Bb5#; 1... Bc5 2. Re5 Bb6 3. Bb5# (2... Bxb4 3. Sb2#); 1... Bd4 (Bb8) 2. Re4 Ba7 3. Sb2#. Other choices of the square for the Rook fail: 1. Rc8? Bc5!; 1. Rd8? Bd4!; 1. Rf8? Bb8!. In each case, capturing the Bishop leads to a stalemate.
