Haas, Ward and Kovacic RIIIIIIP: Gasser, Gas and more Gas

Perusing back through the Deaths in 2015 list under April, I discover the following:

• Walter H. Haas (July 3, 1917 – April 6, 2015) 
• Torrey Ward (July 7, 1978 – April 7, 2015)
• Zdravko-Ćiro Kovačić(July 6, 1925 – April 1, 2015) 

So with the three notable persons born on July 4 among the deaths in 2014 under April so far (see 

previous post, we have a "July 3, 4, __, 6, 7/Date Sequence" pattern-cluster,...  except we need a July

 5 to bridge the gap... which in turn becomes our next lead.   Note from the July 5 wiki page under births: 

• 1888 – Herbert Spencer Gasser, American physiologist and academic, Nobel Prize laureate (d. 1963)
• 1888 – Louise Freeland Jenkins, American astronomer (d. 1970)

They were both born in 1888!!!  Note from their respective wiki pages: 

• Herbert Spencer Gasser(July 5, 1888 – May 11, 1963)

• Louise Freeland Jenkins (July 5, 1888–May 9, 1970) 

Again, we have another "May 9, ___, May 11/ Date Sequence " Pattern cluster... with the missing date being May 10.  

What stands out the most, is the surname "Gasser" coupled with this excerpt from his wiki page:

• During World War I he was engaged in chemical warfare research at the American University

So isn't chemical warfare about using GAS?!
So who exactly, draws  the line on what constitutes a war crime and what doesn't.

As for May 10:

• 1829 – Thomas Young, English physician and linguist (b. 1773)

• Thomas Young (13 June 1773 – 10 May 1829) was an English polymath. Young made notable scientific contributions to the fields of vision, light,solid mechanics, energy,physiology, language,musical harmony, andEgyptology. He "made a number of original and insightful innovations"^[1] in the decipherment of Egyptian hieroglyphs (specifically the Rosetta Stone) before Jean-François Champollioneventually expanded on his work.   

• In 1811 Young became physician to St George's Hospital, and in 1814 he served on a committee appointed to consider the dangers involved in the general introduction of gas into London. 

I decided to check Thomas Young out because his first name means "twin" in origin and so an addition to the "Twin Things" pattern-cluster... a particular inner twin trademark signature.  And then there's his birthday of June 13 which is also my birthday ... and then do note the mention of "gas" in the second excerpt... hence generating a definite "Gas" pattern-cluster.  

One other person that I checked out due to the 22 in his year of birth is:

• 2006 – A. M. Rosenthal, Canadian-American journalist (b. 1922)

That he was also a journalist from Canada resonates ... given the "Targeting Journalist" pattern-cluster.  Note from his wiki page:

• Abraham Michael "A.M." Rosenthal (May 2, 1922 – May 10, 2006)

I'll leave it up to you to find out what is being communicated via the May 2... I'll give a clue-- Toumai.
