Heddiw yw pen-blwydd y diwrnod y rhoddwyd patent ar y teleffon a ddyfeisiwyd gan Alexander Graham Bell, a hefyd y diwrnod pan gafodd yr alwad drawsatlantig gyntaf ei gwneud.
Today not only marks the anniversary of the day Alexander Graham Bell received a patent for the telephone, but also when the 1st ever transatlantic telephone call took place.
