Vaughan was born in South Africa in 1931, and from age six wanted a dairy farm. His parents' small vegetable, flower and poultry farmlet in Durban had a few cows, which impressed him because grass went in, milk, butter, cheese and fertiliser came out, and every year another was born. He bought his first cow when 12 and owned 18 by the age of 23 when he moved to New Zealand. 
He wanted to take an agricultural course, but his mother insisted that he first take a two year Commercial, Economics and Accounting one with Physics. After this took a two year course at Weston Agricultural College, Mooi River, Natal, on its 1,000 ha mixed farm growing everything; vegetables, fruit, poultry, pigs, horses, beef and dairy - all work done by students. He gained honours (99%) in dairying - his favourite subject. The two courses helped him develop a profit-oriented and practical attitude to farming. 

He moved to New Zealand in June 1954, and met his wife Auriel on the boat. They married in October 1955, with Auriel becoming a equal working partner in farming and making farm machinery. In 1955 they bought and converted a run down peat runoff, to milk 28, 45 then 60 cows (average herd size in 1957) to a highly productive dairy farm resulting in being chosen by the NZ Dairy Board as Waikato's most improved dairy farmer in 1959. They invented, designed and made spinner drain diggers, chisel ploughs, bulk spreaders and the first straight-rail, 60 degree angle herringbone dairy. 

In 1968 after Vaughan went to the Australian National Field days to help sell his equipment, they engaged a 50% sharemilker and retired from dairying and then helped start the NZ Agricultural Fieldays. He was made their exhibits chairman, then the first general manager, with Auriel as secretary, of what became one of the world's biggest agricultural events.

In 1979, wanting a new challenge and to export to increase NZ overseas exchange earnings, he consulted for Gallagher, and became Marketing Director, increasing their sales from $3m to $23m in 5 years.  

In 1984 they swapped their 87 ha going concern with their 220 cow sharemilker for a 106 ha bankrupt cropping farm on Greenhill Road, Hamilton, and improved it so much that Ruakura scientists visited it in 1987 and copied things he was doing. 
He has consulted for 500, mostly farmers around the world and is adding his and some of their systems to this eBook. 

At 81 he is still helping grazing farmers make more profit from fewer cows by producing more milk in New Zealand, and less milk overseas after changing from confinement to grazing, with more profit. One subscriber increased profit in four years by $300,000. He improves animal health and eliminates facial eczema (without zinc or medicines) by applying LimeMagPlus to increase earthworm numbers and their vigour which eat the thatch on which facial eczema spores live.
