On August 29th Rob Tijdeman held his valedictory lecture in a full house Academy Building as a professor in Number Theory, entitled 'My life as a mathematician'. After his lecture he was appointed, in name of the Queen, Knight in the Order of the Dutch Lion by the maior of Leiderdorp.
In his lecture Tijdeman looked back, among other things, on a number of highlights in his career so far, such as his results on differences of 'higher powers', and his insight that a variant of the Chinese Remainder Theorem could lead to a breakthrough in the field of Discrete Tomography. In his speech the maior mentioned Tijdeman's great international reputation as well as the many worldwide collaborations he has set up.
