On 25 March 2014 Dr. An Zwollo passed away. She has worked at the RKD from 1956 until 1991. She founded the department of Old Dutch Drawings at the RKD in 1958 and succeeded to make it into a vital part of the institution as a whole in the decades thereafter. She was instrumental in acquiring photographic material from countries in Eastern Europe that were then relatively inaccessible. In the next RKD Bulletin, an in memoriam by Charles Dumas will be published.
