The International Society of Lymphology has a privilege that is hard to find in professional relationships, that is how we are connected to each other as a family.

Unfortunately, from this family we lost two very dear leading and important members who supported and promoted the International Society of Lymphology in its course.

The least we can do for our dear friends and mentors, pioneers in the field of Lymphology, M. Foeldi and W. Olszewski, is to pay tribute to their memory and thus have them with us again.

Therefore, during the 28^th World Congress of Lymphology, which will be held 20-24 September 2021, in Athens-Greece, we have scheduled two sessions with lectures and oral presentations dedicated to their memory.

For this purpose, please propose a lecture/presentation regarding their work and offer to Lymphology or submit an abstract with releative topic.

Looking forward to your participation in the memorial sessions,
