How is current knowledge shaped by its historical development?

This Document records the law of Aurea, signed by the princess of Brazil Isabel, in 1888. The law of Aurea was signed in order to abolish slavery in Brazil, since it was legal until then. This was an enormous historical event that changed Brazilian culture. Although impacts of slavery can still be reflected in the Brazilian society and culture, in positive and negative ways, it was an opener of many doors of opportunity for around 700000 slaves to be freed and live more dignified lifes.

Connecting to the prompt, the knowledge born out of this decree, came in the form of society's perspective on Black people, and how they became exposed to perceiving and treating them as equal to themselves, who were mostly white people, who owned farms, land and of course, slaves. An interesting characteristic of Brazil is its miscegenated population, meaning that its population was formed by people from different races, such as, Indigenous (Native) tribes, Europeans, asians and African people. Moreover, this diversity, that is celebrated and a pronounced characteristic of the country, wasn't born out of the people, it was a process that took time, which required measures, laws, and historical development of these. The Aurea law was a measure that accelerated the development of the space black people had in the society, their rights and equality to other races. Racism will always exist, but in Brazil today, black people are lifted up to succeed by society and law.

As the country developed, so did the population, and the formation of the country resulted in a beautiful place, with all types of races and ethnicities being found, a population with individuals who are completely different from each other. This mixture, came with the historical development of the country, to which led black people being more comfortable claiming their rights, fighting for them politically and socially, and finally, being released from slavery. The place Brazil is now, has changed due to the Aurea Law, which took black people's suffering, humiliation and damage of culture to an end.

This object shows the package of the first chemical hair dye created by Eugene Schueller in 1907 for advertisement purposes. The creation of this commercialised hair dye opened and gave the start to this broad and highly influential hair Industry that is, just like fashion, always in development and contributing to the trends coming year after year. Eugene Schueller named his first commercialised hair dye Aureole, which he later changed to L'Oréal, the name soon given to his company that is now the largest cosmetics and skin care company in the world.

Prior to the creation of a commercialised hair dye, the product (hair dye) itself was invented, by William Henry in 1863, and after that the deriving of a color changing molecule called para-phenylenediamine, or PPD by August Hoffman, which is found in most of the foundations of hair dyes. In short, Eugene Schueller expanded the consumption of the chemical hair dye by commercialising it, and making it accessible, and attractive for consumers.

The way this product's historical development affected beauty cannot be ignored. When, specifically women were given more access to hair products they were getting more opportunities of taking care of themselves, and beginning to influence one another, eventually popularising the practice of caring for their hair. The Aurea Law, can be compared to this object, where its creation brought inclusion, opportunity and accessibility. This also brought attention for studies and discoveries, growing the industry even more and influencing this desire to become younger looking and trendy in multiple manners, making our population highly caring for our hair and its health due to, to a great extent, the confidence it brings to us.

Concluding, the creation of the first commercialised hair dye opened a door into the growth of the beauty industry, advertising it to gain the attention of women, developing hair products (dye, bleach, etc) and eventually building the beauty culture we have now, and influence that makes taking care of our hair and experimenting with it, routine and a part of our culture, and lifes.

This poster is one made by the public relations firm Hill and Knowlton, who were hired by the California Avocado Commission in the 1990s to advertise avocado and its health benefits to the American people.

During the 1980s, U.S dietary guidelines pushed people into a low-fat diet trend. This until the 90s created a huge financial blow in the avocado industry as it was known to have a lot of fat. However, in the 1990s, the California Avocado Commission hired the public relations firm Hill and Knowlton., who went on a search for a mascot for the fruit. The mascot would be called Mr.Ripe, and he was created to promote the fruit and educate the public about it. This made the industry grow immensely, dishes made with avocados were brought into the trend and became part of the, specifically Californian culture. The approach of creating a friendly character related the fruit to the sense of unity and freshness and the not only health benefits but the pleasure of consuming the fruit, and how the foods that were made brought people together. We see this marketing strategy in Object 2, the commercialisation of the hair dye leads to its popularity, both objects had their strategy with the common goal of increasing consumption.

This poster is a mark of a marketing strategy that was created to change the knowledge originally influencing American society, and educating it to be perceived as a healthy fruit, that is now very popular and highly consumed by not only Americans but a wide range of consumers around the world, wanting healthier lifestyles.
