Henry Francis Cronin CBE, MC, BSc (Eng) (1894 – 11 January 1977) was a British civil engineer and army officer.

[4] Whilst serving with the Royal Engineers, Cronin was awarded the Military Cross in 1918 for gallantry in battle at an unspecified location.

He was ordered to follow behind an attacking infantry unit with a section of sappers and to assist with the construction of strongpoints to make the position more defendable.

[5] Cronin reached the front with his men and immediately began the construction of field defences despite being under extremely heavy enemy fire from a flank.

[6] During the period of the London Blitz he worked hard to maintain water supplies, essential for fire fighting and vulnerable to bomb damage.

[10][11] He was a member of the American Water Works Association from 1944 and in 1956 was awarded honorary membership in recognition for his devotion to duty during the London Blitz.
