As a result, Ruchi Ram had to leave Germany hurriedly and went to Manchester in the Lab of Ernest Rutherford who was also mentor of Prof. Kazimierz Fajans.

When he went to Manchester, two of his sons were already in UK, the eldest one was studying medicine at London and his second son Birbal Sahni, a pioneer in Paleobotany was studying Botany at Cambridge. During his vacations, Birbal Sahni assisted his father to produce photographic plates of latter's experiments.
