Samsung Group chairman Lee Kun-hee died early Sunday at the age of 78.
He's widely credited as being the driving force behind the tech giant's spectacular global expansion.
In 1987, at the age of 45, Lee inherited the Samsung crown after the passing of his father Lee Byung-chul, who founded the company.
At that point, Lee vowed to make Samsung strong through innovation.
"I will develop Samsung into a world-class company through challenging and future-oriented management."
In 1993, Lee gathered a group of Samsung executives in Frankfurt to guide them through the corporation's future path.
Known as the Frankfurt Declaration, he demanded major reforms, saying everything must change.
"This is not a joke. Change everything, except your wife and children."
He also stressed the need for quality over quantity, one of his key management philosophies pushing Samsung forward.
To ensure Samsung became synonymous with quality, Lee ordered a bonfire be built to burn 20 million dollars' worth of defective goods to show the company was determined to make quality its over-riding goal.
Under Lee Kun-hee's leadership, Samsung blossomed into one of the world's biggest and most well-known tech companies.
During his three decades as chairman, Samsung Group gained worldwide brand recognition, becoming the leading global player in industries such as TVs, smartphones, and semiconductors.
