The reclusive CEO of Marvel Entertainment was accidentally unmasked by Donald Trump on Wednesday after avoiding having his photo taken by the press for decades.

Isaac 'Ike' Perlmutter, who snatched Marvel assets out of bankruptcy in 1998 and became CEO in 2005, met with Trump at his Mar-a-Lago estate in Florida to help organize a health summit.

But little did the sunglasses-wearing Perlmutter know, Reuters photographer Jonathan Ernst snapped a photo of him and Trump through a window on the property.

If Trump had not brought him to the very front of the property, which is visible to photographers and reporters outside, Perlmutter would not have been photographed.

Unlike most network and studio executives, 74-year-old Perlmutter does not give interviews and reportedly showed up to the 2008 Iron Man premiere in a disguise to avoid being photographed.

But behind Perlmutter's sunglasses and secluded demeanor is a rags to riches story which sees a Israeli Army veteran immigrate to the United States and turn the $250 in his pocket into a $3.9billion fortune.

Perlmutter immigrated to the United States after serving in the Israeli army during the 1967 Six-Day War.

The war was fought for six days in June between Israel and the neighboring states of Egypt, Jordan, and Syria.

Israel launched a series of preemptive airstrikes on Egyptian airfields after it saw mobilization of Egyptian forces along the Israeli border.

Egyptian leader Colonel Gamal Abdel Nasser then joined forces with Jordan and Syria in a fight against Israel - and was militarily humiliated.

In the following days, Israel occupied the West Bank, Gaza Strip, Sinai peninsula and Syria's Golan Heights, and extended its control to all of Jerusalem. On June 11, 1967, a ceasefire was signed.

In the end, fewer than 1,000 Israelis were killed, while more than 20,000 Arab forces died in the fight.

Following the war, Perlmutter left for the United States and arrived in Brooklyn with $250 in his pocket and started selling toys in the street.

His entrepreneurial ways led him into business with fellow Israeli veteran Avi Arad - the pair decided to run a toy company together.

The toy company sold Marvel products, and when Perlmutter saw the company was in decline he suggested that its then-owner Ron Perelman go into film, according to Forbes.

Perlmutter eventually worked his way up to Marvel's board of directors, where he saved the company from bankruptcy in 1998.

The bankruptcy deal valued the company at around $450 million including debt, and in the process of snatching up Marvel assets, Perlmutter outmaneuvered Perelman and investor Carl Icahn - another one of Trump's closest friends, who will advise him in the White House.

He went on to become Marvel Entertainment CEO in 2005 and soon after launched Marvel's plan to produce its own films.

Since taking over Marvel, Perlmutter has transformed the company into a movie-making machine, producing live-action films based on comic book story lines.

Iron Man was the first to be produced and was released in 2008, bringing in a gross total of $318million in theaters.

In the years following Iron Man, 13 films were released in the Marvel Cinematic Universe, featuring other members of the Avengers, including Captain America and Thor, as well as Guardians of the Galaxy and Doctor Strange.

Iron Man was the first of 14 films in the Marvel Cinematic Universe, which was launched soon after Perlmutter became CEO

Seeing Marvel's success, other networks also tried adapting the 'universe' strategy, most recently with DC announcing a Justice League film.

As CEO, Perlmutter has thrived on being secretive and frugal - even refusing to upgrade furniture when Marvel moved from Manhattan Beach, California, to the Disney lot in Burbank.

He was fretting so much about making a profit on Iron Man in 2008, that he wanted to only serve potato chips at the premiere.

And yet, his Marvel Cinematic Universe's 14 films have grossed a total of $4.2billion at the box office, reports boxofficemojo.com.

Perlmutter, who has an estimated net worth of $3.9 billion, according to Forbes, sold Marvel to Disney for $4billion in 2009.

As of 2014, he maintained control over Marvel's operations as well as Disney's decisions on licensing and film-studio management.

'Disney owns Marvel, but Ike gets to control every budget and everything spent on marketing, down to the penny,' a studio insider told the Hollywood Reporter.

While Disney declines to say how much he owns, Perlmutter is one of the top individual stockholders for the company.

But the recluse has also created controversies for Marvel over the years - it's been said that he didn't think anyone would notice if Terrence Howard was replaced with Don Cheadle as War Machine in Iron Man 2 because the hero is African-American, according to the Hollywood Reporter.

Additionally, comicbookmovie.com suggests that Perlmutter could be to blame for the lack of Black Widow merchandise. The character was played by Scarlett Johansson in the Avengers films and was one of the few female roles.

In another incident he was accused of telling Jessica Dunne, then-head of global product licensing in 2012, that he had a bullet with her name on it, the Financial Times reported at the time.

Additionally, the Financial Times reported in 2012 that three African-American executives sought settlements claiming they were offered lesser jobs after a reorganization of the company.

After for his remarks that no one would notice if Don Cheadle replaced Terrence Howard in Iron Man 2 because they're both black, Marvel was forced to release a statement.

The statement said: 'Mr. Perlmutter and all of Marvel have a long record of diversity in the workplace and on movie sets around the world, as evidenced by both Mr. Perlmutter's own history and Marvel's management team.'

Perlmutter did not release his own statement following the incident.

As of September 2015, Vanity Fair reported, Marvel Studios started reporting directly to Disney’s chief Alan Horn instead of Perlmutter.

Perlmutter's current day-to-day operations as CEO of Marvel are unknown, and he still remains as private as ever.

The only previously-circulated circulated photographs of him is one from the 1980s, where he's dressed in a suit and brooding at the camera.

It appears that Perlmutter and his wife, Laura, have been working behind the scenes as Republicans during the presidential election and its aftermath.

The billionaire, who lives between New York and Palm Beach, Florida, was even reported to have celebrated Thanksgiving at Trump's Mar-a-lago estate this year.

Perlmutter donated $1million to Trump's veteran fundraiser in January, according to the Hollywood Reporter.

His wife, Laura, donated $2million to a Super PAC associated with Marco Rubio during the primaries, but after he dropped out of the race she donated $449,400 to a PAC supporting Trump.

After the election she joined Trump's Presidential Inaugural Committee.

And while he has kept his life and business private for decades, Perlmutter might have to get used to the camera if he continues meeting with Trump.

He met with Trump on Wednesday to discuss a health summit - Perlmutter contributed $50million to New York University's Langone Medical Center, where a cancer center is named for him and his wife, according to Bloomberg.

The president-elect allows reporters and photographers to stand outside his estates while he holds meetings with officials, dignitaries and businessmen.

Occasionally, he'll hold impromptu press conferences where he'll address the crowd with whomever he's meeting.

Most recently, he was seen speaking to reporters with boxing promoter Don King at his side outside his Mar-a-Lago estate, and Kanye West in the lobby of Trump Tower in New York.

Trump is currently spending Christmas and New Year at his Mar-a-Lago resort, where he is planning his inauguration.
