Michael Holthouse founded Lemonade Day in Houston in 2007, after building and selling a computer network services company and turning to philanthropy. The organisation's own account names his wife Lisa alongside him and says the programme was established through their family foundation.
One Sunday in one city
The first Lemonade Day ran in Houston in 2007, on the first Sunday in May. The organisation puts its own starting point at 2,700 children in that one city.
Then the model changed, and communities began buying licences to run their own Lemonade Day, each setting its own date. Its national president, Steven Gordon, wrote that with as many as 80 communities holding licences the day had "evolved far beyond just one day or one weekend". What it calls a "Lemonade Season" typically runs from late April through early September.
