Before the conglomerates, there was Family business. Before the Industrial Revolution in the early 18^th century, there was family business. Before the erudition of the Chinese, Greece and the Roman Empire, there was family business. In the post-war era, management experts expected family firms to wane fast, due to the greater ability of professionally-run companies to raise funds and attract top talent. Founding dynasties have held their ground, defying expectations of their demise, and in the recent years, increased their global presence.

In a study by Center for Family Business, the 500 largest family-owned businesses make up 80-90% of firms worldwide and 19% of the companies in Fortune Global 500, and are salient drivers of GDP and job growth. In the Global Family Business Index, the list of who’s who of brands worldwide: Wal-Mart, Ford and Tyson are all present, as are lesser-known companies like Diersch&Schröder,a German mineral oil company that employs only 350 people and yet pulls in $2.5 billion in incomes. With hard work and sacrifice, they have set the foundations of deep-rooted family culture and entrepreneurial spirit that are pinned to a multigenerational family business.

Here are five founding dynasties spanning over a hundred years, across more than three generations that we find incredibly noteworthy.

Charities run by Buffett’s three children Howard Buffet, Susan Alice Buffett and Peter Buffett, and one named for his deceased wife – Susan Buffett - will receive Berkshire stock – a total of $6.4 billion.
