Necessity is the mother of invention. In the mid-1900s, with Australian farmers battling fly infestations and soldiers in the Pacific encountering malaria-harbouring mosquitos, Doug Waterhouse developed an aerosolised insect repellent he called ‘Aerogard’. A visit from the Queen led to a public demonstration that got the attention of the international market, Aerogard™ was snapped up by Mortein™, and Doug’s invention is now an essential summer companion for millions worldwide. But without a visiting monarch, who’s going to be there to find the next Aerogard™?
