White House to /[ö]\ House, PART 48

On the 20/20 Wikipedia page, is a list, two of which stand out.  First there’s the 20/20 vision wiki page where we are able to retrieve the following:

• Ferdinand Monoyer (9 May 1836 – 11 July 1912) 
• Heinrich Georg Küchler (23 April 1811 – 29 March 1873) 
• Eduard Jäger von Jaxtthal (June 25, 1818 – July 5, 1884)
• Theodor Karl Gustav von Leber (29 February 1840 – 17 April 1917) 
• Gustav Theodor Fechner (19 April 1801 – 18 November 1887)
• Ernst Heinrich Weber (24 June 1795 – 26 January 1878) 
• Stanley Smith Stevens (November 4, 1906 – January 18, 1973)
• Louis Leon Thurstone (29 May 1887 – 30 September 1955) 
• Landolt, Edmund, (17 May 1846 – 9 May 1926)
• Ignaz Paul Vital Troxler (August 17, 1780 – March 6, 1866)
• Herman Snellen (February 19, 1834 – January 18, 1908) 

There are a number of clusters, with two adding to a recent cluster:

 “January 18(x2), __, March 18, ..., July 18, __, September 18, October 18, November 18, December 18(x3)/ 18th Day, Date Sequence” pattern cluster..

 The most prominent to me personally, is the “April 17(x2), __, 19 ..., 23/Date Sequence” pattern cluster, given that my son-in-laws birthday is April 17.

The second one listed on the site that stood out :

• Vision 2020: New York City Comprehensive Waterfront Plan, an initiative to develop the waterfront of New York City, New York, U.S.

•  Michael Rubens Bloomberg (born February 14, 1942) 

• Amanda Jay Mortimer Burden (born January 18, 1944)

• Christine Callaghan Quinn (born July 25, 1966)

• Daniel Hudson Burnham (September 4, 1846 – June 1, 1912) 

Interesting, Bloomberg is a democratic running for leadership of the party!!   Note the name Burden... and her date of birth:
“January 18(x3), __, March 18, ..., July 18, __, September 18, October 18, November 18, December 18(x3)/ 18th Day, Date Sequence” pattern cluster..
