Background: John Harvey Kellogg, M.D. (February 26, 1852 - December 14, 1943) was an American medical doctor, nutritionist, inventor, health activist, and businessman. He was the director of the Battle Creek Sanitarium in Battle Creek, Michigan. The sanitarium was founded by members of the Seventh-day Adventist Church. It combined aspects of a European spa, a hydrotherapy institution, a hospital and a high-class hotel.
Context: Although they are less discussed than his food creations, Kellogg designed and improved upon a number of medical devices that were regularly used at the Battle Creek Sanitarium in surgical operations and in treatment modalities falling under the term "physiotherapy". Many of the machines invented by Kellogg were manufactured by the Battle Creek Sanitarium Equipment Company, which was established in 1890. Dr. Kellogg attempted to popularize these treatment methods, including electrotherapy, hydrotherapy, and motor therapy, in his work The Home Handbook of Domestic Hygiene and Rational Medicine, first published in 1881. As he specialized in certain gynecological surgeries (particularly hemorrhoidectomies and ovariotomies) and gastrointestinal surgeries, he developed various instruments for these operations. These included specialized hooks and retractors, a heated operating table, and an aseptic drainage tube used in abdominal surgery. Additionally, Kellogg took keen interest in devising instruments for light therapy, mechanical exercising, proper breathing, and Hydrotherapy. His medical inventions spanned a wide range of applications and included a hot air bath, vibrating chair, oscillomanipulator, window tent for fresh air, pneumograph to graphically represent respiratory habits, loofah mitt, and an apparatus for home sterilization of milk. Some of his inventions were fashionable enough to be included in the first class gymnasium of the RMS Titanic. As in other areas, Dr. Kellogg did not make concerted efforts to profit from his medical inventions. Kellogg's statement in 1916 about his food company sheds light on his general motivations: "I desire to make clear...that the food business I have been carrying on is a part of my general scheme to propagate the ideas of health and biological living. Otherwise, I should not have engaged in it as a commercial enterprise, but I have carried it on as a part of the general philanthropic work in which I was engaged."

Background: Jacob Gedleyihlekisa Zuma (Zulu: [gelZhejile'kisa 'zhuma]; born 12 April 1942) is a South African politician who served as the fourth President of South Africa from the 2009 general election until his resignation on 14 February 2018. Zuma is also referred to by his initials JZ and his clan name Msholozi. Zuma served as Deputy President of South Africa from 1999 to 2005, but was dismissed by President Thabo Mbeki in 2005 after Zuma's financial adviser, Schabir Shaik, was convicted of soliciting a bribe for Zuma. Zuma was nonetheless elected President of the African National Congress (ANC) on 18 December 2007 after defeating Mbeki at the ANC conference in Polokwane.
Context: Thabo Mbeki filed an affidavit and applied to the Constitutional Court to appeal Pietermaritzburg High Court Judge Chris Nicholson's ruling: It was improper for the court to make such far-reaching "vexatious, scandalous and prejudicial" findings concerning me, to be judged and condemned on the basis of the findings in the Zuma matter. The interests of justice, in my respectful submission would demand that the matter be rectified. These adverse findings have led to my being recalled by my political party, the ANC - a request I have acceded to as a committed and loyal member of the ANC for the past 52 years. I fear that if not rectified, I might suffer further prejudice. Tlali Tlali, National Prosecuting Authority spokesman, stated by phone from Pretoria, on 23 September, "We have received the papers. It's under consideration." The judgement for the appeal was handed down on 12 January 2009 at the Supreme Court of Appeal in Bloemfontein. Deputy Judge President Louis Harms had to rule on two aspects of the appeal. The first aspect was whether or not Zuma had the right to be invited to make representations to the NPA before they decided to reinstate charges of bribery and corruption against him. The second aspect was whether Judge Nicholson was correct in implying political meddling by the then President Thabo Mbeki with regards to the NPA's decision to charge Zuma. On the question of the NPA's obligation to invite representations when reviewing decisions, Harms DP found that Nicholson's interpretation of section 179 of the Constitution was incorrect in that the NPA did not have such an obligation and thus was free to have charged Zuma as it did. On the question of Nicholson's inferences of political meddling by Mbeki, Harms DP found that the lower court "overstepped the limits of its authority".
