根据福克斯新闻社的报道，德利加蒂认为麦当劳是时候售卖那种更大的“更适合成年人吃的汉堡”，这样才能够与另一家本地快餐连锁店Eat'n Park竞争，Eat'n Park当时推出的是名叫"Big Boy"的大三明治。
The iconic burger was created by franchisee Jim Delligatti of Pittsburgh, Pennsylvania, in 1967.
According to Fox News, Delligatti believed that McDonald's should sell a larger burger "geared towards adults" in order to compete with another local fast-food chain, Eat'n Park, which sold a "Big Boy" sandwich.
His burger debuted on April 22, 1967, and featured a "double burger" with a bun in the middle, a slice of cheese, lettuce, onions, and a secret "special sauce."
The Big Mac is arguably McDonald's most iconic menu item, but few know how the burger actually got its name.
Since 1967, the Big Mac has been satisfying McDonald's customers with its two patties, three buns, and secret "special sauce."
Here's how the Big Mac came to be and got its famous name, plus how the burger has changed over the years.
关于这款汉堡要叫什么名字，大家纷纷参与了讨论。还有另外两个名字的选择是Aristocrat（“贵族”汉堡）和Blue Ribbon Burger（“蓝带”汉堡），但这两者后来都没有被采用。
When the company decided to roll the burger out across the US in 1968, a 21-year-old secretary came up with its name.
There was a lot of deliberation over the name. Two other options were the Aristocrat and the Blue Ribbon Burger, but both were nixed.
However, Esther Glickstein Rose, a 21-year-old secretary for the company's advertising department in 1967, had the winning name - "Big Mac."
According to the AP, executives and other employees at the time laughed at the name. However, it stuck and went on to become "one of the best-known product names of all time."
Esther Glickstein Rose wrote to the chain many times to try and get them to give her credit for the name.
No one believed she had actually come up with the name - not even her own children.
However, Esther Glickstein Rose was finally recognized in 1985 for coining the name. She never asked for nor received any payment for naming the burger, but did receive a plaque engraved with a Big Mac and a thank-you note.
"I felt that because of her perseverance all these years, the fact that it really is for her kids and the fact that, yes, indeed, she did play a role in naming the sandwich, we should recognize her," said Jeff Olian, a McDonald's lawyer at the time.
