19188 Dittebesard           Discovered 1991 Dec. 30 by E. W. Elst at Haute Provence.
Ditte Besard (1977-2010), eldest daugher of Camilla and artist Hugo Besard, died after a struggle over many years. Implicitly remembering the goddess Eunomia, her father expressed his feelings as follows: Hour after hour, day after day, time comes downwards like falling snow and covers the present with a carpet.
