Tributes have been paid to Alan McQuillan, a mainstay of RTÉ Radio programming, who passed away suddenly on Wednesday. 
   
Jim Jennings, RTÉ Director of Content, said: "Alan was well known and respected throughout RTÉ and was a talented member of our Radio family for almost 20 years. 

"We will miss him dearly, and we send our thoughts and condolences to his family and to his many friends both inside and outside RTÉ."

In an appreciation, Alan McQuillan's colleague and friend Dave Timpson wrote: "The passing of Alan McQuillan yesterday has come as the greatest shock to those who knew him. 

"Alan was ubiquitous to the Radio Centre in every way. His wonderful kind character and his work ethic touched everybody and everything that came from radio, both on and off air. 

"Across all stations presenters were desk trained by Al, pre-recorded programmes were scheduled by Al, outside broadcasts were operated by Al.  

"In addition to Al becoming a regular on Radio 1 continuity, he was one of the longest serving on-air voices synonymous with weekend music on 2fm. Al was truly a radio man.

"He had a very particular and professional approach to everything in his working life. He was beloved of all who knew him. His kindness, warmth and selflessness in dealing with his colleagues was one of his greatest strengths.

"A strength that earned him the friends for life he made in RTÉ, an RTÉ that he adored. Nobody understood the building and the people within it like Al, reflected in the sheer panic each year when Al would announce his annual leave dates.

"The Radio Centre is an emptier place in his absence and without him we are truly off air."

A book of condolences has been opened in the reception of the RTÉ Radio Centre.

Jenny Greene, who worked closely with Alan, reflected on Alan's passing in conversation with RTÉ's, Adam Fogarty on the Nicky Byrne Show with Jenny Greene on 2fm on Friday morning.
