The International Society of Heterocyclic Chemistry (ISHC) was established in August, 1968, in Albuquerque, New Mexico, in the USA by Dr. Raymond N. Castle (1916-1999). The function of the society is to promote heterocyclic chemistry, in particular by serving as the primary sponsoring agency for the ISHC-Congress, a large biennial meeting attracting up to a thousand participants. Further aims of the ISHC are to honor persons who have made outstanding contributions to the field with two distinguished Awards and the appointment of ISHC Fellows. The ISHC is also actively involved in the publication of “Progress in Heterocyclic Chemistry” (PHC) a major reference work on heterocyclic chemistry published annually since 1989.
