Ryszard Jaxa-Małachowski Kulisicz (Odessa, May 14, 1887 — Lima, September 6, 1972), later known as Ricardo de Jaxa Małachowski, was a Polish-Peruvian architect, active in Peru for nearly all of his professional career.

He was immediately put to work by President Augusto B. Leguía, who asked him to design and install the sacristy of the chapel of the Government Palace.

In late 1933, Malachowski was almost killed during a robbery near Villa María School in Arequipa Avenue, today the Alliance Française.

Malachowski wrote the book, Lessons of Elements and Theory Of Architecture with the intentions of putting all his teaching material into one place.

He taught the course of Elements and Theory of Architecture at the Escuela Nacional de Ingenieros (National School of Engineering) in Lima between 1915 and 1944.
