لينوس باولنغ
وهذا العالم فاز يعتبر واحد من اكثر علماء الكيماء اثرا على مر التاريخ وقد فاز بجائزة نوبل في الكيمياء ثم فاز لاحقا بجائزة نوبل للسلام وبذلك يكون الوحيد الذي فاز بجائزتي نوبل ولا يشاركه في ذلك احدا ويلاحظ انه يتيم الاب في سن التاسعة
.
لينوس باولنغ
(
بالإنجليزية
: Linus Carl Pauling) ـ (ولد في
28 شباط/فبراير
1901
ـ
19 آب/أغسطس
1994
). هو كيميائي وفيزيائي أمريكي، يعتبر من أول الفيزيائيين الكميين المتحصلين على
جائزة نوبل في الكيمياء
، وذلك سنة
1954
.
السياسة
لم يكن للينوس أي انتماء سياسي. خلال الحرب العالمية الثانية قام بتطوير متفجرات ووقود صواريخ. كما قام بعمل جهاز قياس الأوكسجين في البحارات الأمريكية. عندما بدأ
مشروع مانهاتن
عرض عليه
روبرت اوبنهايمر
أن يكون مدير قسم الكيمياء للمشروع ولكنه رفض. تحصل سنة
1948
على ميدالية من يدي
هاري ترومان
لمساهمته في الجيش الأمريكي. لكن إلقاء القنبلة النووية على
هيروشيما
وناغازاكي
أثر فيه فانضم إلى هيئة الطوارئ لعلماء الذرة بقيادة
ألبرت أينشتاين
وكان الهدف منها توعية الرأي العام من أخطار السلاح النووي. قاد نشاط لينوس باولنغ السياسي إلى رفض منحه جواز سفر سنة
1952
لحضور مؤتمر علمي في
لندن
وأعيد له جوازه قبل سفره لتسلم
جائزة نوبل
سنة
1954
.
حصل على عدد كبير من الجوائز من بينها جائزتا نوبل، أولاهما في الكيمياء سنة
1954
، والثانية في
السلام
سنة
1962
لحملته ضد التجارب النووية، كما حصل على
قلادة بريستلي
سنة
1984
.
Linus Carl Pauling
(February 28, 1901 – August 19, 1994)[ was an American
chemist
,
biochemist
,
peace activist
, author, and educator. He was one of the most influential chemists in history and ranks among the most important scientists of the 20th century.
[
Pauling was one of the founders of the fields of
quantum chemistry
and
molecular biology
.
[7]
For his scientific work, Pauling was awarded the
Nobel Prize in Chemistry
in 1954. In 1962, for his peace activism, he was awarded the
Nobel Peace Prize
. This makes him the only person to be awarded two unshared Nobel Prizes. He is one of only four individuals to have won more than one Nobel Prize (the others being
Marie Curie
,
John Bardeen
, and
Frederick Sanger
). Pauling is also one of only two people to be awarded Nobel Prizes in different fields, the other being
Marie Curie
.
[8]
He promoted
orthomolecular medicine
,
megavitamin therapy
,
dietary supplements
, and taking large doses of
vitamin C
.

c.
1900.
Pauling was born in
Portland, Oregon
,
[9]
[10]
as the first-born child of Herman Henry William Pauling (1876–1910) and Lucy Isabelle "Belle" Darling (1881–1926).
[11]
He was named "Linus Carl," in honor of Lucy's father, Linus, and Herman's father, Carl.
[12]
Lucy's great grandfather William Darling, Sr., has a documented lineage to Elder William Brewster, who arrived in America on the
Mayflower
, and it is used as a sample lineage.
[13]
Linus Pauling spent his first year living in a one-room apartment with his parents in Portland. In 1902, after his sister Pauline was born, Pauling's parents decided to move out of the city.[ They were crowded in their apartment, but could not afford more spacious living quarters in Portland. Lucy stayed with her husband's parents in Lake Oswego, while Herman searched for new housing. Herman brought the family to
Salem
, where he took up a job as a traveling salesman for the Skidmore Drug Company. Within a year of Lucile's birth in 1904, Herman Pauling moved his family to Oswego, where he opened his own drugstore. The business climate in Oswego was poor, so he moved his family to Condon in 1905.
[ By 1909, Herman Pauling was suffering from poor health and had regular sharp pains in his
abdomen
. His health worsened in the coming months and he finally died of a perforated
ulcer
on June 11, 1910, leaving Lucy to care for Linus, Lucile and Pauline
At age nine, Linus was a voracious reader. On May 12, 1910 his
father wrote a letter to
The Oregonian
inviting suggestions of additional books to occupy his time.
[4]
Pauling first planned to become a chemist after being amazed by experiments conducted with a small chemistry lab kit by his friend, Lloyd A. Jeffress.
[17]
At high school, Pauling continued to conduct chemistry experiments, scavenging much of the equipment and material from an abandoned steel plant. With an older friend, Lloyd Simon, Pauling set up Palmon Laboratories. Operating from Simon's basement, the two approached local dairies to offer their services in performing butterfat samplings at cheap prices. Dairymen were wary of trusting two boys with the task, and as such, the business ended in failure.
[
By the fall of 1916, Pauling was a 15-year-old high school senior with enough credits to enter
Oregon State University
(OSU), known then as Oregon Agricultural College.
[19]
He did not have enough credits for two required American history courses that would satisfy the requirements for earning a
high school diploma
. He asked the school principal if he could take these courses concurrently during the spring semester, but the principal denied his request, and Pauling decided to leave the school in June without a diploma. His high school,
Washington High School
in Portland, awarded him the diploma 45 years later, after he had won two Nobel Prizes. During the summer, Pauling worked part-time at a grocery store, earning eight US dollars a week. His mother set him up with an interview with a Mr. Schwietzerhoff, the owner of a number of manufacturing plants in Portland. Pauling was hired as an apprentice machinist with a salary of 40 dollars per month. Pauling excelled at his job, and saw his salary soon raised to 50 dollars per month. In his spare time, he set up a photography laboratory with two friends and found business from a local photography company. He hoped that the business would earn him enough money to pay for his future college expenses.[ Pauling received a letter of admission from Oregon State University in September 1917 and immediately
gave notice
to his boss and told his mother of his plans
