INTERNATIONAL SOCIETY 



OF DEVELOPMENTAL BIOLOGISTS (formerly I.I.E.) 



(Developmental Biology Section of the I.U.B.S.) 



The I.S.D.B. announces with deep regret the death of its emeritus member 

 A. Kiihn (Tiibingen), and of its member K. Bier (Miinster). 



In accordance with the decision taken by the latest General Assembly the 

 I.S.D.B. is sponsoring a number of small Workshops on important problems in 

 developmental biology to be held in different parts of the world. Attendance 

 will be limited by invitation to a small group of participants, but will also be open 

 to a number of local observers. 



The first of these Workshops was devoted to "Morphogenetic tissue inter- 

 actions" and was held on September 2 — 4, 1969 in Helsinki, Finland. Dr. 

 L. Saxen was chairman of the local organizing committee.There were 32 parti- 

 cipants from 14 countries, and 14 local observers. The Ministry of Education 

 of Finland acted as co-sponsor. Several other Workshops are in the active 

 planning stage. 



At present the I.S.D.B. has 454 members; 139 new members were accepted 

 by the Board in 1969. A complete membership Hst is given below. The Board 

 should like to see the membership become [ully representative o[ developmental 

 biology, and therefore earnestly solicits proposals as well as spontaneous appli- 

 cations for membership. The procedure is as follows: 



a) Candidates for membership can be proposed or supported by two members 

 at any time. The Board screens the applications once or twice a year, and decides 

 about acceptance by simple majority of votes among its members. 



b) The requirement for membership is that the candidate should have made 

 a substantial contribution to the field of developmental biology. The Board 

 decides whether a particular applicant meets this standard. 



c) Proposals must be accompanied by a curriculum vitae and a list of publica- 

 tions of the candidate, and should be sent either to Prof. E. Zwilling, Dept. of 

 Biol., Brandeis Univ., Waltham, Mass. 02154 .U.S.A., or to Prof. P. D. Nieuw- 

 koop, Hubrecht Laboratory, Uppsalalaan 1, Universiteitscentrum "De Uithof", 

 Utrecht, Netherlands.
