The move recognises “their 30-year career as the leading developer and operator of diving centres at four locations on the Sinai coast of the Red Sea”.

Sinai Divers runs centres in Sharm el Sheikh, Dahab, Marsa Alam and Aqaba.

“Petra and I have been nominated and chosen as the first Germans in the diving industry to join the International Scuba Diving Hall of Fame,” said Schmidt.

“This would not have been possible without loyal, hard-working and trusted partners, employees, clients, friends and families who supported us throughout these years.”

The pair will travel to the Caymans, along with four other inductees, for the induction on 12 November.

The ISDHF has made annual inductions since it was founded in 2000 by the Cayman Islands Ministry of Tourism.

The late Bernard Eaton, founder of DIVER magazine and the Dive Shows, was inducted into the ISDHF in its first year.
