Kasper died at the age of 77 in July, after stepping down as FIS President a month earlier.

At the FIS virtual Congress in June, Kasper was named an Honorary President.

He had led the organisation for 23 years, having been first elected as President in 1998.

This followed a 23-year stint as secretary general from 1975.

Kasper was also a member of the International Olympic Committee (IOC) from 2000 until 2018, when he became an honorary member.

The ceremony is scheduled for December 12, following the conclusion of the women's super-G event at the FIS Alpine Skiing World Cup.

The FIS said the ceremony will aim to "formally recognise all that Gian Franco Kasper did for the world of international skiing and snowboarding," with former colleagues, Olympic medallists, former world champions and World Cup winners among those invited to St Mortiz.

A minute's silence was also held prior to the first FIS Alpine Skiing World Cup of the season in Soelden in Austria at the weekend (October 23 and 24), while the IOC plans to honour Kasper at its Association of International Winter Federations meetings next month.

Michel Vion, the secretary general of the FIS, said the plans in St Mortiz would be a fitting tribute to the governing body's long-serving President.

"We can think of no better way to honour the memory of Gian Franco Kasper than bringing the friends and family of FIS together on the snow in his hometown at a FIS World Cup race," Vion commented.

"We hope this will give our FIS family the chance to reflect on Gian Franco’s legacy and pay tribute to him in way that we know he would fully appreciate."

Tributes were paid by the IOC President Thomas Bach and Association of National Olympic Committees secretary general Gunilla Lindberg when the news of his death was announced earlier this year.

Staff at the FIS also held a traditional Swiss Znüni - a mid-morning snack - featuring coffee and croissants in his honour.
