Final answer:
Bioethics is associated with Hippocrates, known as the 'father of Western medicine,' who laid the groundwork for medical ethics with the Hippocratic Oath.
Step-by-step explanation:
The field of bioethics is closely associated with the Greek physician Hippocrates, who is often referred to as the "father of Western medicine." Hippocrates believed that diseases had natural causes rather than supernatural ones, laying the groundwork for medical ethics by focusing on treating patients with the intent to do no harm as expressed in the Hippocratic Oath. The term 'bioethics' itself, however, was coined much later in the 20th century by Van Rensselaer Potter, a biochemist who expanded the discussion to include ethical issues arising from advancements in biology, technology, and medicine.
