We lost Prof. Dr. Ahmet Vefik Alp, one of the volunteers of the Marmara Group Foundation. Ahmet Vefik Alp was a valuable friend of ours who took part in the studies of the Marmara Group Foundation as an academic. We wish mercy to our friend, whose memory we will always preserve, share the rightful pain of his family, and wish patience to the Marmara Group Foundation community.
