This paper extends the DMP inverse introduced in [the reviewer and \textit{Y.-M. Wei}, Appl. Math. Comput. 141, No. 2--3, 471--476 (2003; Zbl 1033.15003)] from matrices to operators on Hilbert spaces. The main tool used here is a triangular matrix representation for a bounded linear operator and its Moore-Penrose and Drazin expressions.
