. From this stemmed a major chemical fertiliser industry, of national importance to the agricultural and pastoral economy. For almost a century 'K. P.' was to dominate the market. Prosser resigned from the company in 1886 and went to Australia before committing suicide.

By the mid-1970s, some New Zealand farmers decided it was time to take control of the fertiliser industry, and established a new company, the Ravensdown Fertiliser Co-operative Ltd. With help from Brierley Investments and producer board funds it acquired Kempthorne Prosser in 1978, and Kempthorne Prosser exited the market.

Kempthorne Prosser operated four large chemical works. The Burnside, Dunedin Works (1881), Westfield, Auckland (1887), Hornby, Christchurch in 1922 and the Aramoho, Wanganui (Wanganui Chemical) Works in 1926.

Chemical works and buildings

In 1870 the firm erected its first premises, on Stafford Street, City Rise, Dunedin. This row of three joint buildings still stand today on the lower reaches of the street, below the SaveMart Building, which was the Kempthorne Prosser laboratory

, Australia. He worked briefly as a labourer digging up tree stumps. In 1855 he found a position in the wholesale drug trade. On 23 June 1859 in Melbourne he married Sarah Inman. They had five daughters and one son before Sarah's death in 1895.

Kempthorne arrived in Dunedin in April 1863, sent by the Melbourne pharmaceutical firm of H. & E. Youngman to look at the prospects of establishing a warehouse there. When the company's managers died Thomas Kempthorne stayed in Dunedin and set up his own drug business, French Kempthorne & Co (after going in partnership with a Mr French). It did not last very long and in 1870 Kempthorne, Prosser & Company was formed when he went into partnership with Evan Prosser, a Welsh chemist on the West Coast. The partnership prospered and in 1879 they set up a limited liability company with capital of £200,000.

He became a prominent figure in the Dunedin business community, remaining managing director of Kempthorne, Prosser & Company until 1904 when he retired.

Subsequently he removed to Dunedin, where, with Mr. Kempthorne, he formed the nucleus of the since-important firm of Kemptorne, Prosser and Co. Mr. Prosser afterwards retired from the firm and went to Sydney. He was the second Mayor of Hokitika, and held office in the year 1868. He was in business in Hokitika as a chemist and druggist, and subsequently became an original partner of the well known firm of Kempthorne, Prosser and Company, Limited.

 at the North Shore, Sydney, on the 20th 1896. The event is thus reported in the Sydney Daily Telegraph: — A deliberate case of suicide and attempted murder occurred at Neutral Bay shortly after noon yesterday, when Mr. Evan Prosser shot himself at his residence, Raymond-road, and afterwards twice fired at his wife. About minutes after 12 yesterday Mrs. Prosser, having heard the discharge of firearms, immediately ran upstairs, and, going into the bedroom, saw her husband lying on the floor, with blood flowing from under his right ear. She endeavoured to raise him to Ms feet, but while doing so he pointed a revolver towards her and fired two shots, one of the bullets grazing her neck. She eventually managed to get possession of the revolver, and immediately sent for Dr. Shirlow, who, upon his arrival, ordered the removal of the unfortunate man to the North Shore Hospital, where attempts were made to locate the bullet by Drs. Shirlow, Clarke, and Rorke. When the revolver was handed to the police it was discovered that four of the chambers had been discharged. Mr. Prosser retained his consciousness until he arrived at the institution, when he collapsed, and expired about 4 p.m. Mr. Prosser, who was 60 years of age, was at one time connected with the late firm of Messrs. E. Prosser & Co., wholesale druggists, of Sydney, which business passed into the hands of the Australian Drug Company some years back. The matter was reported to the Coroner, who ordered an inquest.

Products

Some of Kempthorne Prosser's most well known material:

KP/Kempthorne Prosser's products were popular in New Zealand. K.P. Lifesalt was a drink offered in the late 1920s until at least the 1940s when Andrew's Liver Salts gained the market. KP also produced flavouring essences in up to eight different flavours.

KP Rockland and Westfield Manures were celebrated manures produced at the Burnside and Westfield Works in Dunedin and Auckland. From 1881 until about 1920 Kempthorne Prosser held a monopoly in the fertiliser division in the country until competition existed.

KP supplied major chemists and hospitals throughout New Zealand.
