Broadcaster and author Eusebius McKaiser has been described as a courageous thinkers, irreplaceable and one of the greatest teachers in South Africa.

Friends, colleagues and family of McKaiser gathered in Parktown on Tuesday for a memorial service to pay tribute to the late media icon.

He died last month after suffering an epileptic seizure at home at the age of 45.

McKaiser worked for Talk Radio 702, Power FM, TimesLive, while he also contributed to the Mail & Guardian and Sunday Times amongst others.

"He was an intellectual rockstar, looking at what we do today [podcast], I think he was our plan. There are so many things we wanted to do with him that we are not going to be able to do," said TimesLive editor Makhudu Sefara.

"There is no one that we are going to find to replace Eusebius, he is not replaceable. You can find bits, pieces elsewhere in other people but you will not find what he brought to the table as an individual.

"He was a true patriot, not ANC and DA defined patriots, but a true patriot because he wanted what was good for the country. His last tweet talks to that."

McKaiser published several books, including A Bantu In My Bathroom and Run, Racist, Run.

Fellow Broadcaster Joanne Joseph called on the mourners to take the literary legacy forward.

"I ask all here to do something substantial for the course of literacy in memory of Eusebius, he accomplished so much in this short space of 44 years. We no longer him but we still have his words, and we will still have the essence of you in them."

Close friend and renowned broadcaster Redi Tlhabi told mourners that Eusebius had an "agenda" to bring change to society.

"Eusebius had an agenda, and I say that without any fear of contradiction. His agenda was to speak out for the underdog, amplify his voice against bigotry, was to put himself between that fatal strike of power and corruption.

"Between the protagonists and those who would be victims of such a strike, including a South Africa that was progressive, thriving, delivering for people and that was home to all of us. That is what Eusebius's agenda was."

Close Friend and Journalist Karyn Maughan described McKaiser as "brilliant" and an "extraordinary and gifted intellectual who could debate the big questions of life with you".

Maughan said that she always walked away from conversations with him knowing more. At heart, she said, he was "one of the greatest teachers that this country has ever known".

He demanded excellence from himself and the people blessed enough to have engaged with him in the spaces that he occupied," she said.

He was not selfish in his intellect or his success. He 'lifted as he rose' and he's one of the people that embodies that saying more than anyone else I knew."
