The ceremony was held in the Tel Aviv Museum (today known as Independence Hall) but was not widely publicised as it was feared that the British Authorities might attempt to prevent it or that the Arab armies might invade earlier than expected. An invitation was sent out by messenger on the morning of 14 May telling recipients to arrive at 15:30 and to keep the event a secret. The event started at 16:00 (a time chosen so as not to breach the sabbath) and was broadcast live as the first transmission of the new radio station Kol Yisrael.
