In 1925,G. F. LAUGHLEN, M.D. was  the first [[physician]] to describe [[lipoid pneumonia]]. He first interacted to the disease by routine [[autopsy]] at the Toronto, Ontorio hospital for sick children. He described grayish red nodules at the autopsy with three types of [[Exudate|exudates]], found out [[Monocyte|mononuclear]] cells which were unexpected in the [[Exudate|exudates]]. In 1949 McDonald et al described endogenous [[lipoid pneumonia]] for the first time. He observed so called "obstructive [[pneumonia]]" in patients with [[Lung cancer|lung neoplasms]].

Overview

In 1925, G. F. LAUGHLEN, M.D. was the first physician to describe lipoid pneumonia. He first interacted with the disease by routine autopsy at the Toronto, Ontario hospital for sick children. He described grayish red nodules at the autopsy with three types of exudates, found out mononuclear cells which were unexpected in the exudates. In 1949 McDonald et al described endogenous lipoid pneumonia for the first time. He observed so-called "obstructive pneumonia" in patients with lung neoplasms.

1875 Edwin Klebs identified bacteria in the airways of individuals who died from pneumonia.
1848 Carl Friedländer identified the two common bacteria such as Streptococcus pneumoniae and Klebsiella pneumoniae that cause pneumonia.
1893 Veillon was first to write about the role of anaerobic bacteria in aspiration pneumonia.
1896 Roentgen described x-rays.
