H.J. Lam, 25 years Director of the Rijksherbarium

For twenty five years the tie between the two sister-institutions, the Herbaria at Bogor and at Leyden, has been growing stronger. Great distance, financial trouble and political upheaval have not been able to prevent the continuous development of the spirit of co-operation towards a common ideal: The advancement of botanical science. In no small measure this is the merit of the Director of the Rijksherbarium, Professor Dr H.J. Lam, who has always been the rock against which the waves of difficulty broke.
