entire family I can't see a thing but

you can hear and smell everything every

breath every sneeze every cough that

hits your face this is life in a 19th

century city there's a story of 19th

century American history which is about

progress the rise of America to becoming

a great economic power but there's a

pretty grim underbelly to that story and

that is a really shocking rate of death

to infectious diseases America in the

1700 is to a large extent a country of

Hamlet's and villages and small towers

with a few cities which are slowly

growing come the 1800s cities like

Boston and New York are doubling and

doubling again technological innovation

was thriving

titans of business like Rockefeller and

Carnegie for growing industries at

unprecedented rates railroads were

transporting people and things faster

machines were making things more

efficiently than humans ever had in

history this was quite literally a

revolution tons of new jobs were created

but here's the thing the cities weren't

ready for all those people so places

like New York City ended up packing

these newcomers and to cheap apartments

or tenements they were small and rarely

had windows so there was no light or

ventilation houses are overcrowded

they're working in factories that

breathing on one another that

contaminating one another with their

germs and also with VCS that's right

feces that's because there weren't

proper sanitation or sewer systems or

clean water supplies very rapidly people

are starting to drink water which

contains feces from their neighbors

through a number of diseases that

claimed a lot of lives

the most serious were respiratory

illnesses and the biggest killer of all

was tuberculosis tuberculosis killed one

in seven in the United States in Europe

at this point people came to suspect

that their living conditions influenced

their health they began to argue if you

want to combat diseases you've simply

got to clean up the slum areas in fact

in New York in the 1830s they have

people sweep the streets and this has

the Helle beam dump the decades and

they're amazed to find that underneath

all the muck and the film and the

decomposing animal bodies the rattling

cobblestones

they're all doing this because they

believe in my asthma's these gases that

rise up from decomposing matter which

they believe somehow cause sickness but

the efforts of clean cities got a major

push in the late 19th century when

doctors and scientists were able to

prove that diseases were not caused by

my asthma's but by germs one of those

doctors was Robert Koch Robert Koch was

a German general practitioner who in his

spare time when not treating patients

devoted endless hours to investigating

disease under the microscope he

discovered that specific germs caused

specific diseases but he's probably best

known for his work in tuberculosis

he discovered the germ responsible and

found that it's transmitted through the

air now that people realize what causes

infectious disease they have every

incentive making sure that people have

clean water when you wash your hands you

wash away many of the disease-carrying

smudges you may have picked up and they

have sewage pipes to take away the

effluence

Wallace leads to is large-scale civil

engineering projects across America due

to the improved access to clean water in

the first few decades of the 20th

century US cities saw an estimated 50%

drop in mortalities laws were also

passed to reform housing in the cities

to ensure residents had sufficient light

and proper ventilation in their homes in

less than 20 years the death rate from

tuberculosis plummeted from one out of

every seven to more like one in 1,000 in

the United States Robert Koch even got a

Nobel Prize for the impact of his

tuberculosis research life generally was

getting better and better for Americans

knowing that germs cause disease was a

significant component of that
