Mercedes Gleitze was the first person to undertake the Irish Channel in 1928.
Mercedes arrived in North Down where thousands of people turned out to catch a glimpse of her. During the summer of 28 she attempted the North Channel 3 times. Unfortunately she did not succeed in her personal struggle to champion the crossings of all crossings. The news paper reports at this time stated that it could never be crossed.
No one tried again till 1947 when Tom Blower successfully made both shores.
