Pietro Angelo Secchi

Died 26 Feb 1878 at age 59 (born 18 Jun 1818).Pietro Angelo Secchi was an Italian priest and astronomer, a Jesuit, who made the first survey of the spectra of over 4000 stars and suggested that stars be classified according to their spectral type. He studied the planets, especially Jupiter, which he discovered was composed of gasses. Secchi studied the dark lines which join the two hemispheres of Mars; he called them canals as if they where the works of living beings. (These studies were later continued by Schiaparelli.) Beyond astronomy, his interests ranged from archaeology to geodesy, from geophysics to meteorology. He also invented a meteorograph, an automated device for recording barometric pressure, temperature, wind direction and velocity, and rainfall.[DSB gives birth date 18 Jun 1818. EB gives 29 Jun 1818.]

Lost Rooster

The priest in a small Irish village was very fond of the chickens he kept in the hen house out the back of the parish manse. He had a cock rooster and about ten hens.
One Saturday night the cock rooster went missing and as that was the time he suspected cock fights occurred in the village he decided to do something about it at church the next morning.
At Mass, he asked the congregation "Has anybody got a cock?" - all the men stood up.
"No No" he said "That wasn't what I meant. Has anybody seen a cock?" - all the women stood up.
"No No" he said "That wasn't what I meant. Has anybody seen a cock that doesn't belong to them." - half the women stood up.
"No No" he said "That wasn't what I meant. Has anybody seen my cock?" - all the nuns stood up.
