Born in Amsterdam, Loman lived in London for a number of years.

He played chess for money against rich Englishmen, like his Dutch pupil Jacques Davidson.

Loman returned to the Netherlands and, in 1912, he became Dutch champion (the 2nd official NED-ch in Delft).

[2] In matches he drew with Paul Saladin Leonhardt (+4 −4 =2) at London 1904, lost to Johannes Esser (+0 −3 =1) in 1913 (the 3rd NED-ch, play-off), and lost to Edgar Colle (+1 −2 =2) at London 1922.
