His first jobs included selling newspapers on street corners, selling ads in trade magazines, and serving as a court reporter.

Adelson first started making big money in trade shows. He launched COMDEX, a technology trade show in Las Vegas, with partners in 1979.

The trade show became one of the most attended in the world, and in 1995, Adelson and his partners sold it along with other smaller shows to SoftBank for $US862 million.

Adelson didn’t get into the casino business until he was 55 years old. In 1989, he bought the Sands Casino & Hotel in Las Vegas for $US128 million.

He demolished the hotel in November 1966.

It took two years and cost $US1.5 billion to build The Venetian.

To imitate Venice, Italy, Adelson ordered detailed renderings of the Doge’s Palace, Rialto Bridge, and Campanile tower.

He also enlisted the help of a historian from Venice who worked with the hotel’s architects and interior designers.

The Venetian opened in April 1999. It just celebrated 20 years on the Las Vegas strip.

“The Venetian’s success in Las Vegas, and particularly our convention-based business strategy, would end up being the basis for our company receiving coveted licenses in Macao and Singapore,” Adelson said in a statement to the Las Vegas Review-Journal, a newspaper he owns.

In 2004, Adelson opened the Sands Macau, which cost at least $US265 million to build.

It opened in 2004 as Asia’s first “American-style” casino and went on to become “extraordinarily successful,” according to Forbes.

Adelson is also in the media business.

In 2015, he bought the Las Vegas Review-Journal for $US140 million.

The newspaper was among a handful of publications that endorsed Trump in the 2016 election.

Both were divorced when they met in the late 1980s.

It was reportedly Miriam’s idea to make The Venetian in Las Vegas Venice-themed after the couple vacationed in the Italian city for their honeymoon.

The Adelsons live in a megamansion in Summerlin, an affluent Las Vegas planned community.

Adelson reportedly owns an Airbus A345, which he once used to set a record for the longest flight ever to depart from Israel’s Ben-Gurion International Airport. According to Haaretz, he made a 17-hour and 40-minute flight from Israel to Honolulu, Hawaii, in 2017.

Adelson is a major donor to Republic politicians.

Adelson gave at least $US17 million in political contributions to Gingrich during his 2012 presidential campaign, according to The New York Times.

Adelson has made at least $US25 million in political contributions to Trump, earning him the nickname “Trump’s Patron-in-Chief.”

The Adelsons wrote checks amounting to $US20 million during Trump’s campaign and donated an extra $US5 million for the inauguration festivities, according to ProPublica.

“I would put Adelson at the very top of the list of both access and influence in the Trump administration,” Craig Holman of the watchdog group Public Citizen told ProPublica in 2018. “I’ve never seen anything like it before, and I’ve been studying money in politics for 40 years.”

Adelson is also a major donor to Jewish organisations.

He’s given $US410 million to the Birthright program that provides funding for trips to Israel for young Jewish adults, according to Forbes.

In March 2019, it was reported that Adelson was being treated for non-Hodgkin’s lymphoma.

Ron Reese, a spokesman for Adelson’s company, told Fortune that Adelson was experiencing side effects from his medication.

“These side effects have restricted his availability to travel or keep regular office hours,” Reese told the magazine in a statement. “They have not, however, prevented him from fulfilling his duties as chairman and CEO.”

In April, the casino mogul made $US2.2 billion in one week thanks to his property in Macau.

The Las Vegas Sands’ share price rose 8.8% on one week thanks to significant gambling revenue in Macau, according to Forbes.
